DraStic

I figured it out, I went into the phones storage and found a duplicate . Apk file, I deleted it and it worked, thank you for your help anyway.

I have tried both of those, but it doesn't seem to work...

I downloaded the drastic free demo for my HTC desire 601, and it worked brilliantly. I then paid for the full version and it Installed on my devic. Whenever I try to open the full version it immediately kicks me out and gives me the error message drastic has unfortunately stopped.
What do?
Please ...
