ZETA+2 PROBLEMS AFTER INSTALLING EXPANSION PACKS

Everything was running smoothly until I installed these expansion packs: Xenos Soundworks Bundle for Z3TA+ 1.5 and 2 AND Z3TA 2 and Free Mutant Patches. When I open a track that has previously used other patches in ZETA they no longer work,(or you get a horrible buzzing sound) even though they are in the correct folder and can I see the FXP files for them. I get... Error: Program data load failed Installed exactly as recommended, have uninstalled and reinstalled ZETA and the expansion packs again. Just when everything finally seems to be running smoothly I get this ****... AARRRRGGGGHHHHHH Suggestions more than welcome.
