Unable to start VuGen

Hi,

I have a problem on my machine when I am trying to start VuGen.

The message I get is:

Exception of type: System.IO.IOException. Source: mscorlib. Occured in Void WinIOError(Int32, System.String) method
Exception message is: Het bestand bestaat.

After this message is shown for about 2 seconds an other messagebox is displayed with:

[Window Title]
VuGen

[Main Instruction]
VuGen werkt niet meer

[Content]
Er wordt naar een oplossing voor het probleem gezocht...

[Annuleren]

Does anyone know what might be causing this, and/or how it can be solved?

It worked last Friday, but after a crash of VuGen this obstacle arose.

Regards,

Jeroen
