AAE error - 30001 Missing plug-ins Track... Transfuser

So i spent hours on a project and when I tried to reload it it came up with:



Missing or inactive plug-ins

Track "Inst 2" Insert A ("Transfuser") has been made Inactive because a AAE error was encountered.

AAE error -30001 was encountered..



I deleted transfuser from the session, saved it then relaunched and now when I try to insert a new Transfuser track it comes up with the same AAE error -30001. I load up other sessions where transfuser was used and it works no problem, I create a new session, insert a new Transfuer..no problem. Its just this one session I cant use Transfuser on. And now im stuck with a session I cant put any beat to.:mad:



Looked up error 30001, but none recorded in knowledge database.



The only thing I did differently from other sessions is I used battery wavs in transfuser instead of factory. But surely deleting it and starting a new instance would work. I dont get it. Many years Ive used this [bleep][bleep][bleep][bleep] and still it mystifies me...and infuriates.
