Thanks scook but i can't find that file. I'm assuming it's located on the hard drive (not the registry)?

It is a directory
Open Windows explorer and type "%appdata%\overloud" in the path entry or search Windows for "%appdata%\overloud"
This will resolve to the appdata\roaming\overloud folder in your user directory. Appdata is a hidden directory.

scook
rename or delete %appdata%\Overloud\TH3
then reinstall the Boutique FX Suite
there is no registration required for TH3 Cakewalk

I had the same issue right after the update to TH3. I think what is causing the problem is if you unknowingly click on the "full version" trial, it gives you 30 days then requires a serial.
SCOOKS suggestion worked for me, after numerous unsuccessful attempts at rolling back and forth.
Good Luck!

scook you are indeed an absolute star! It worked. Not sure what caused the problem in the first place though rworkman? Certainly don't recall installing a trial version. 
 
Thanks again guys. Much appreciated!

is it possible to save posts for future reference? I'd like to keep this one somewhere!

TH3 Cakewalk has the full version trial built in. It is pretty easy to activate the trial version.

Sure you can save the page on your PC. Most browsers have a save page option. Alternately, you can bookmark the page in the browser. save the permalink http://forum.cakewalk.com/FindPost/3493340 to a text file of tips or use the search string "site:forum.cakewalk.com yellowcake64 th3" in Google the next time.

Thank you!
