k, i seem to have fixed it
it was idd WebStats 1.2 that isn't compatible with the new LFSLapper 3.8 yet
new LFSLapper uses like "XFG", but (old) WebStats is still written to search for "XF GTR"
and with "BMW" and "FXO", there needs to be one space behind in webstats to work (the PB.txt file contains "BMW " and "FXO " (mind the space at the end))
now one last problem; !top XFG works, but !top BMW doesn't
i think it's a related problem, but should be fixed in LFSLapper source code i think, but i'm not planning to do that now
(the use of "BMW " should be replaced by "BMW" i think, and same for some other cars too)
