Can't install apps

[thrash994]

I bought L1320 today and I have updated it to the last Preview version. Now I have a big annoying problem, I can't install apps on my SD card neither on phone memory whatever I try. I have already done a reset and also formatted the SD card. Still nothing good. I've been restarting my phone all over and over but the app is still there installing but not actually installing and when my screen times out there's no other way to start the phone than restarting it. I'm so much pissed off right now!
I have no idea what else to do with it. If anyone can help I'd be really glad.
