QT plugin library, pretected with trialware, not works

[sh0375]

Hello,

I protect dll with QT plugin using installshield 2009 trialware feature.
When i used QT 4.3.3 everything worked fine.

Now i build my program in QT 4.5 and it refuses to load dlls, wrapped by InstallShield trialware - receive error when loading plugin library.

Unhandled exception at 0x10001047 (backgrou.dll) in program.exe: 0xC0000005: Access violation writing location 0x01b389ef

protected backgrou.dll:
