Hi,I have fs9.1, I have installed on my pc a new video card (from ati 9600xt to ati x800 gt), new video driver but now when I launch fs2004 I receive an error on sim1.dll.How I can resolve?? please help me!!

There's a lot of possibilities for this error but since you just installed a new video driver this is probably the problem. Uninstall and reinstall the video drivers and see if that fixes the problem. You might also do a search on this forum using "sim1.dll" as your keyword. This error has been discussed quite a bit.Jim
