I rarely post here so apologies if this is a common problem - I have searched for an answer!
I have CS4 Master Collection loaded on my main PC and my laptop. They are both test installs as I use CS3 and an Axio LE card for my main edit system on XP. I have installed the one copy on both machines as I intend to either use it in the office or on location, deactivating the one I'm not using.
However today I noticed on the Matrox forum that there is an update for CS4, so I tried to force the update by going to 'help - update' but it was greyed out along with the activate/deactivate button. So I went to my laptop and it was the same!
Strangely I can open BOTH the main PC and the laptop versions of Premiere at the same time!
I can even download the update directly from the Adobe site and it says it cannot load.
Can anyone enlighten me on this?
Yes it is a fully legit paid for version!
Looks like your installation went corrupt.
Deactivate, uninstall, run CS4 2 or 3 times, reinstall, reactivate and update may solve the issue.
