Try reinstalling using DM. Hopefully you made backups!?!
Where did you buy it? If you bought it from the Crackberry/Mobihand store the you can sign into your account & re-download to the phone.
If you bought it from AppWorld I've read about several issues getting things resolved. But I don't buy from AppWorld so maybe someone can help you there.
Or write customer service & they can send you a download link in an email.
Good luck.
