ZRev crashes Ableton!?

[Citrixx]

ZRev crashes Ableton - opening the plugin in Ableton Live 10 appears only white screen -clicking a button crashes Ableton. Had it installed with Zebra several days ago, worked fine since today. Any idea? Thanx

Hmmm, ZRev opens fine here in 10.1.

ok, so far i can tell that im able to use it as long i have the zrev.dll and the zrev(x64).dll file in the same folder - in my case the vst-x64. other u-he plugins i usually have each in the 32/64 folders without any problem so far and thus i can even rename them without having that (x64)-ending.
zrev makes problems in that case as far i can see. i reinstalled zebra, no difference. thx

If you had previously renamed the ZRev plugin, and then installed Zebra again, you would end up with multiple versions of ZRev installed, and Live will decide which one to load. This can lead to the plugin opening with a white GUI under some circumstances.
Don't just reinstall Zebra over the old installation, instead first check Live's preferences, in which locations it looks for installed plugins, then search all those locations and delete all ZRev instances you find. And then do a fresh installation.
And make sure you are not installing Zebra into the program files location, because this can lead to the white GUI issue.
