Hello, I am having problems with registering my FSUIPC key. I tried looking up previous posts but found nothing regarding my problem... The problem is I downloaded the MSFS 9.10 patch and then downloaded software called FS2ATCS from ATC simulator. The creator said the key provided should work, but it isn't. Also said that all we need to do is register an application key, tried that and it didn't work. Seems to me that we need to register the FSUIPC including name, email address, and key. I've done everything I am supposed to so far, like move the FSUIPC.dll and FSUIPC.key files to FS modules. Sorry if I haven't explained myself clearly and sound dumb, but when it comes to this stuff, I am. So, if anyone knows what is going on or has heard of similar problems please help me out. Thanks.
