I can install free apps but I can't install apps that I have purchased before it says couldn't install on usb storage or sd card. Anyone know what is causing this?
Welcome to Android Central
Sounds like the apps are trying to download to the SD card rather than internal storage for whatever reason. Did you set that up when downloading apps?
Sorry for the extremely late reply. Glad you were able to get it working again
