nexus 7 not downloading actualisations from google play.

Hello!

From few weeks my tablet doesn't want to download actualisations from google play... It doesn't have a problem with downloading any files from internet... But fom google play is not actualising. I have turned on all the data transfer, downloading with WiFi and mobile data... It looks like... It wants to download actualisations but its not. When I'm accepting actualisations it is starting to download but its not showing how much data left or time... And it can be in this starting stage forever. I have planty space in my storage and in memory.
What should I do?
Help please

Well... I did as you said... I cleaned all the cache, and storage data... And it didn't work... I turn the tablet off and on again... And this stupid actualisations still doesn't work...

Well that was funny... It works for first 30 sec. One actualisation was downloaded... But nothing else... And now it doesn't work again... A logged in to my first account ... And latter again to the new one... Doesn't work.

Do you mean to remove completely my accounts... From internet ... Totally... and than make my account from new.. again?

... nope... still no change...

Oh... Now I'm starting to be worry... Nothing works...
Could it be because I didn't gave any payment details when registering google account?... All of my applications are free so I don't need to give my payment details...

Well... it doesn't work neither.. on the web site iv'e got information that " application will be installed on my device soon" and than its this same on my tablet... its starting without time and mbs ... its lasting for long time in "my applications" in google store but not downloading... and yesterday it showed me error 495. I've tried to fix it by solutions what i found for this error but it also didn't work.
soon i won't be able to do any thing on my tablet because all of the applications will need actualisation and it can't take it.

wow... something new. in settings>users> I added new user...second one.. and there play store works.. but second user is not main one and it doesn't have the applications which i have and i can't actual. them over there... I can't also remove or change the main user ( the owner) ...what does it mean and what can i do wit it.

Browser? I don't know... Because I have two and and I never could download anything with chrome but with the another one I never had problem... I can download anything.

any way...of course I can't download any other browsed because on my android i can get apps only by google store... and i can't download any thing from it... and if i'm trying with normal file.exe my android can not read it.

play.google?? and whats that? because i've got: google play books, google play games, g.p. movies, g.p newsstand, g.p. services, g.p. store, but no play.google :]

Yes!!! I did it... It finally works... All I had to do is:
Reset App Preferences:

This trick has worked according to some users and here is how you have to Reset App preferences in your Android device to fix error 495.

Go to Settings and then tap on Apps
Now you can see the list of Apps which are present in your device
Press the Menu key on your android device
This will bring a pop up box with the Reset App Preferences option which should be selected
Then you have to again tap on Reset Apps option

Thnx everybody for trying to help me... I hope it will help somebody else to... Bye
