Hello Markus,
thank you for your fast response!
Unfortunately neither nor did help.
Solution 1: Under windows by default, you can't remove the write protection. You can uncheck the mark, but it comes back every time. Anyway, the files are there and the standalone version loads pretty fast. I tried a reinstall twice (Solution 2) but that didn't change anything either. I don't know, I think it is a problem with Acid Pro, since I don't have this problem with Reaper, where Gladiator opens instantaneously.
Thanks for the answer, win xp and Acid pro 6 are really old anyway, it was just nice to have the other Tone2 synths run fine even on such an old system...
Cheers
Dumbo
