Greetings Peter,
since almost one year now I am having trouble with FSUIPC. I have FS9.1 and an unregistered version of FSUIPC v3.99 installed and at the beginning (don't know which version of FSUIPC it was back than) I got this error message every now and then:
But with the time it got worse and I got that message in two of three Flightsim starts. Now I installed v3.99 and fired up FS2004 ten times in a row and got that message EVERY time!
I don't won't to blame FSUIPC for this problem since I have alot of addons installed, but maybe you can help me finding out what is causing this trouble.
EDIT: I forgot to mention that I have done absolutly no configuration with FSUIPC, I only have it installed since several airplane addons require it!
Thanks
Nicolas
