@ Sinclvire,
Without some details we would only be guessing. Can you tell us:
-- the exact folder path where the MP2 program was installed
-- the exact folder path(s) where the MP2 plug-in(s) were installed
-- the exact folder path where the MP2 Sounds library was installed
The Sounds should not be installed in the same folder as the program or VSTi. Somewhere completely outside C:/Program Files is OK. Or, even, better, on a different disk / SSD.
@ hoozerob,
Same questions. Also did you mean your last sentence to read "So anyway, I cannot load any instruments or any files at all."?
