Apps from BB AppWorld not working

Hello, I recently downloaded an app "IP Cam Viewer 10" for my playbook from BB Appworld, by paying Indian Rupee 185INR. But it is found not working; A black screen appears with BB symbal beneath which shown a message "Initializing, Please wait". after some 1 or 2 minutes, it comes to home screen. i hope this is android based apps and not working for current latest OS2.0.1.358. Please clarify why there are apps which does not work in Playbook and we are loosing money???? or else what I have to do? I have read in some forums that to downgrade to OS 2.0 (first version of OS2.0).
