I have just purchased WOFF PE. I deleted all mods then installed it. On clicking 'Go to Field' from the flight briefing it starts to load then a small error box appears says 'Distance Calc Error' and then CTD.
I have no idea what that means. I also did a complete uninstall and started from scratch. WOFF UE, WOFF PE and the 5.01 patch, but still the same error and CTD. This only happens in campaign.

If you have a non-english OS, and you have applied the 5.01 update then see section 5 of the WOFF FAQ
http://www.overflandersfields.com/index_html_files/FAQ%20WOFF%20UE.pdf

Try that please.

If still a problem send all the Log files, pilot, dxdiag and sysinfo as per the last 2 pages of the FAQ to support email please.
