I do not need a solution (just sharing information)
So I upgraded the CMS 7.5 installation to Hotfix 1.
Unfortunately, Deployment Solution 7.5 Hotfix 1 doesn't recognise the Deployment Solution license and has gone back to trial mode.
Pretty poor show when I have valid maintenance and licenses until 2015.
I've check the license certificates and confirmed that the Deployment Solution license is installed.
Services have been restarted.
Service call has been logged - now just waiting to see if Symantec can fix this before the trial expires!
Thankfully I haven't upgrade production yet!
