Im having a lot of problems with Live 7.01 and my vst plugins.
I reported a bug the other day about it not recognising my Ronin plugin until i moved it.
Now i've got problems with Jamstix 2, either it
A: wont load, live says its 'incompatible'
B: crashes with access violation errors
or
C: the UI for the plugin doesnt respond (which causes live's ui to not respond) and im stuck with the audio playing and no way to quit except via killing the app / process in the task manager.
i've written a bug report on the JamStix forum as well, but its definitely something between JS2 and Live 7 because JS2 runs perfectly in Plogue Bidule. (except when i then load the PB VST into live with JS2 in it, then im back to more crashing and errors...oh and the ui mouse handling behaviour is really jumpy with JS2.)
I also had a 'plugin not found' problem the other day when no matter which plugin i tried to add it complained that it couldnt find them, this was part way through working on a set and i already had instances of that plugin in the set from earlier (this time it was Altiverb 6).
