I'm having a problem when opening QTP, it shows a pop-up message which reads: vb_init - Not able to find starting point of DLL SetVbGlobal in vb_trap.dll

Although after acepting the message, it allows to work in QTP normally, when running from Quality Center that error message sometimes hungs the probe. I already tried to replace the .dll from a probe that works OK and re-installing the QTP but still the same problem.

Any suggestions how to solve the problem?
