Reaper Scanning Vst Plugins

Basically I start up Reaper, make a new MIDI track, and insert Miroslav 2 into it. Whenever I play notes from my MIDI keyboard, they respond with the loaded instrument, but they never turn off. And even if I get it to stop by either pressing the exclamation point or the play button twice, those notes that I had played previously will no longer respond for the entirety of the session. I have confirmed that it is Miroslav 2. All other VSTis work - and my keyboard/piano is brand new.
Using Windows 7 64 bit Pro. 32 gigs of RAM.
Can someone please help.
EDIT: It is quasi resolved now as I had to switch to the VST2.

For a while REAPER has been crashing often when I insert a plugin. This is NOT normal behavior and not what I am used to seeing. After a dozen crashes this morning I stopped trying to mix and tried to figure it out. Cool free vst plugins.

Reaper Stuck Scanning Vst

Clearing the plugin cache didn’t help and neither did installing the latest update. Eventually I found a preference that I normally have enabled was actually disabled. Vst plugin jazz percussion. This option is called ‘Bypass audio while opening plug-in config window‘ in the Plug-ins>VST settings.

The good news is REAPER doesn’t crash anymore, the downside is playback glitches momentarily when inserting a plugin or opening the UI (which is the reason I disabled it before).
If REAPER is crashing often, give this a try.
