Hi Folks,I discovered that RC4 has a default WX Freq of 118.00 every time it does not find the airport WX freq in the f4.csv file I guess.Now, every time I am within the right distance to the arrival airport and otto goes to check the weather and does not find the right freq, it uses this default and my FS9.1 crashes with the error message about the atc.dll I just tried to find the 118.00 freq in the f4.csv file without success! So, why doesnt know RC4 the right weather atc freq of all the airports which have one???And what to do about these crashes? I do NOT like to fly for hours and crashing just befor arrival!_______________________Regards, Torben HadlerBeta-Tester ACLoader 3 + 4http://www.fsflightdeck.com/acloader.htmlT-A-H MultiMedia Productions Torben Hadler - http://www.t-a-h.com || [email protected]: CPU: AMD 64 Socket 939 +4000 | MoBo: MSI K8N Neo2 64 | RAM: 2048MB 400MHz DDR | NVIDIA GF7600 | Creative Sound Blaster Audigy 2 ZS 5.1Ch | CH-YOKE + Peddals; Primary: 17" Belinea TFT * Secondary: Philips 150S4 TFT 15" || Software: Display Resolution used: 1280x1024 in WinXP and FS9.1 | WinXP Pro SP1b (German Version); DX9c | FS9.1 pro (German Versions) - all sliders maxed about 85-95% | ever latest FSUIPC licenced | ASv6 | Alert!! pro | UT 2004 | RC4.x | FSBuild 2 | ACLoader 4.x and much more...

these atc.dll crashes (which are ms not me) was fixed by a fsuipc version.what fsuipc version are you running?you can always go to the controller's page, and put whatever frequency you want in for the atis frequencyjd

I have the latest version for fs9.1

HelloAdd RemoveATC=Yesto the GENERAL section of your FSuipc ini file, this will cure the ATC.dll crashes.

does that prevent the ai from doing what they are supposed to do?jd
