Problem with VoIP applications

[Pavel Troller]

Hi!
  I was trying to run FreeCall VoIP client, however, it detects a problem
and tries to contact its authors. I've done a bit of googling and I've found
that there are at least 3 similar programs (FreeCall, VoipCheap, VoipDiscount)
which behave exactly the same way, they are using probably the same client.
Also AppDb lists at least one of them, with identical symptoms. 
  There is the following report generated by wine:

  The preloader warnings are harmless in this case. I think the ole errors
are the real cause.
  I don't need to use the program for calling, just to make a registration to
FreeCall - they offer also the web-based registration, but then they don't
allow to pay with PayPal - "for better security" :-(.
  Any chance the program could be started at least to allow the registration ?
