I ran into a problem with Flux's Bittersweet Pro. I updated both Sonar Platinum and BS pro to the latest version and then Sonar started to complain about BSPro. Decided to uninstall and install it again. Now when I run the Plugin Manager it freezes while reading the BS Pro and nothing happens. Does any one have any idea how to get the plugin manaher to read the BS?

whenever I've had an issue like this, it is normally because the plug in is corrupted / not compatible / not authorised etc - unfortunately I don't have any Flux Plug ins so cannot test - I assume once you remove it, everything works OK?? 
How are Flux plug ins authorised - could it be an issue there??
If not this sounds like an issue with Flux so maybe get onto them?
Sorry can't help more

This is an odd issue. Neither Sonar Platinum nor Reaper will scan the plugin. No error messages during installation of BitterSweet Pro. The license is on iLok so no problem should be there. And before updating to the latest version everything worked just fine.
 
Well, email Flux support. Will be interesting to see what they say.
