I just ran into this. After running the 2005 melbourne mod for quite some time I decided to install the sepang update. It seems that all of the sepang updates, I.E. Hi res, med res, low res will not run also. They all drop me back to desktop at the completion of track loading. No matter what car setting i have in the graphics option.
As soon as i go back to the original melbourne set in the drop down box in the lower left corner of csm1.25 everything is ok and runs fine.
What is the major differance in the sepang update and the original melbourne release?
The sepang update gives me the same problem as the 2004 mod.
Please. do you have other ideas?
