Nuendo 5.5 activation code issue resolved

Hello There,
I have just upgraded from Nuendo 3 - 5.5.3 and I have an issues with the following.

Application ‘LoopMash 2’ has caused the following error:

eLicenser(s) contain no valid license for this application.

My eLicenser shows NEK 5 so I can only assume that an additional code is required.

I have checked my mySteinberg account but I don’t see a code.

can you please help

Regards

De
