i cant download any game since last ea app update

In this case, if you can see the games in the library in a different device with the same account, that indicates that there might be a local issue on your device. 

I suggest that you use Ccleaner to remove the EA app and install it again on your local device.

To delete them, you can try using CCleaner to clear out issues and errors.

For instructions on how to use Ccleaner to uninstall apps, click here.

While we suggest using CCleaner, EA does not provide user support for this program–use it at your own risk. Please follow any installation guides straight from CCleaner when installing and performing program set-up. You can find help on CCleaner’s support page.

ok so i donwloaded ccleaner. and when i try to remove ea app. the ea app opens and after choosing unitall it says couldnt complete install. error code INST-21-577
But if i uninstall it from control panel then it is able to uninstall the app

this is wat is shows when i try to remove it from the ccleaner app. but from the control panel it has no such issues unintalling

Ok so once you reinstall the EA app, please try clearing its cache:

1. Open the Start menu.
2. Open All Apps.
3. Find the EA folder and click the downward arrow to expand.
4. Select App Recovery.
5. A confirmation window will pop up.
6. Click Clear Cache.
