Right so after 2 days of fiddling, I worked out where that "Debug Assertion" error is coming from - Basically the RealityXP_WX500 gauge that is installed in the Gauge folder when you run the installer, is the wrong one - you´ll need another version. Thats all that I had to change. PM me and I´ll send you the file. The file that I have, size is 476.04 and is dated 29/08/2005.
