VSTi Issue with v3.02

I just went from 2.58 to 3.02. I am using several VSTis where the UI is displayed just fine when you click on the FX button. However the Pianoteq UI just locks up reaper 3.02 and is not completely displayed. Pianoteq works fine in 2.58. Any ideas besides going back to 2.58? :-)

I downloaded the trial of Pianoteq 3.0.4 and the GUI looks fine in Reaper 3.02. Can you give more specifics about the problem?

I reinstalled Pianoteq and it seems to be working now. Perhaps the DLL became corrupted somehow. Thanks!
