RX8 (64bit) works! Oh, now it doesn't

Prior to Audacity 3.0.x, I had to use RX8 as a stand alone, export my file, import into RX8, process & re-import into AUD to edit.

The new 64 bit AUD 3.0.5 fixed all that. RX8 works like a dream (most modules). Until an RX8 update last weekend. Clicking the Effect opens the RX8 module (De-Click), but selecting the audio track to process, hitting apply does nothing. >Edit>Undo shows nothing happened.

I unloaded the modules, reloaded them, and now they won’t load into Audacity. What else can I try?

Only install VST2 versions. (VST3 not currently compatible with Audacity).
