I dont have access to update my Lightroom

Hi - Im registering /buying a new Lightroom package on my computer through my own email. The last one I had was through the school I was studying at.
The problem is that Im trying to update to the latest Lightroom version but always get the "updates have been disabled for this machine, Please contact your administrator"
I re-registered last night and still have a pending message that I will soon be able to access the plan
Is there anything I can do or can you help me fix this?
