I need Advynia for edit SMA3 levels

Hello guys, I have a problem, I can't start Advynia for edit SMA3 ROM, it appears the error message:

This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: minimal, offscreen, windows.

Help!

I want to use this tool, please.

From a quick google search, this problem is usually caused by another program running on your PC. Have you tried running Advynia without any other applications open?
