after installing it through the BandLab Assistent app only to end up in demo mode

It might be useful to know what OS, BandLab Assistant and CbB version this post is about. Have you tried logging out of BA and back in?

I am having the same problem after months of use with no issues- I have done all my installing and uninstalling via the bandlab app and I am logged in correctly to bandlab but I can’t get out of demo mode. It might be a coincidence but I installed the hotfix today ( everything was fine yesterday) I am running win 10 and the latest cakewalk version....

Hi, my error code was 4.1

Providing detailed OS, BA and CbB version info may be helpful.
 
Assuming logging out/in with BA does not activate CbB - after uninstalling CbB make sure to delete "C:\ProgramData\Cakewalk\Cakewalk Core" before reinstalling.

If anyone ran into this issue please log out of BandLab Assistant then fully exit the application from the menu (not by clicking the x). Then start it up again and log in. After that the app should be activated.
Sorry for any inconvenience. There was a temporary back end problem that has been resolved that affected new activations only.

Thank you Noel- and thank you to Ashwin on your help desk , all working now!

=>  "log out of BandLab Assistant" : how, where ?
=> "fully exit the application from the menu" : I'm guessing "the application" means Cakewalk, but which menu?
=> "Then start it up again" : what is "it" here? Bandlab Assistant or Cakewalk?
 
This activation thing is making it so complicated, where everything used to be so simple...
