So, this is what I did, just before
mortal's most recent post, through assistance from
Bigbrother;
Initially the problem seemed to be with textures of
RedBullRacing, so as I was advised I deleted the folder of
RedBullRacing.
I also deleted
Wadcache folder.
Then copied a clean
cars.wad file into the main GP4 folder.
So fingers x'd I run GP4 through CSM (as usual) &.............. GP4 FINALLY works fine, but of course with
RedBullRacing cars in the default green
Jaguar team colours & model (as I had deleted the
RedBullRacing folder).
I exit GP4, & again run GP4, this time..... GP4 crashes again...... seems like the problem now is to be with textures of
Sauber.........
So I do the same thing all over again, after deleting the folder of
RedBullRacing, I now delete the folder of
SauberI also deleted
Wadcache folder.
Then copied a clean
cars.wad file into the main GP4 folder.
&........ finally GP4 runs at least.......... but of course
RedBullRacing cars in the default green Jaguar team colours &
Sauber in default GP4
Sauber team colours & car model.
The only other problem I have is that the Mercedes F1 Team has the front wheels 'in front of the suspension & hubs'.
Conclusion, in all GP4 is finally running at least, but without 2012
RedBullRacing cars &
Sauber & also with a "handicapped"
Mercedes F1 TeamAny more suggestions?
