I'm actually trying SL360 since we think to update our SL3 to SL360. This morning I worked with SL3 and everything was fine. I had to make a test in SL360 so I opened it and it had two updates. Then after my test I tried to go back in SL3 and now it's asking for activation. I entered my SN and it keep telling me my SN is invalid.
Help! I need it ASAP since I have a ton of work to do!
