Constant installation issues.

Please, I really need help.

I have tried uninstalling, and reinstalling.

When I update the app and load it, instantly I am prompted with a reccurring "New update available" once I press update, I log back on and whatever, I can use it.

Then sometimes I'll get program issues it'll freeze or such, then forced to re-update.

My computer is plenty good enough to run Photoshop, it's just this Beta which has been giving me issues.

What can I do about this, I'd like to clear out ALL photoshop temp and main files and give it a good clean up so hopefully it stops giving me these issues.
