Hello, I have recently had to switch to a new laptop at work. The IT person did transfer programs, files etc. Acrobat was a bit tricky as he had to look around to find an installer as apparently this is not supported anymore. Anyway he did deactivate the version on the old laptop (not sure if this was done prior to trying installing on the new machine or after). Anyway, he managed to install this on the new machine however everytime I open it, it says that the serial number is already in use by the maximum allowed computers and I need to deactivate another computer within 30 day. I take the 30 days is what I have left for using Acrobat on this machine with this (not so friendly) pop-up. Any idea on how to fix this? Of course, the serial number I'm using is valid and it is the same that was used on the old maching when the company purchased the software.
