Default Storage issues.

My problem is simple. All apps are 0.00b. I dunno what I did but it just happened. Any solutions or help will be appreciated. Thanks in advance! (:

Edit: can't seem to install any apps either. Wiped cache and dalvik cache too.

Smack that thanks button If I helped!
Always make a nandroid backup before trying anything risky
