CS5 Serial Number not Valid
I have CS5 Master Collection DVD Pack. I had it installed on and old PC. I removed it and deactivated it from that PC to installed on a new PC. Now when I input my Serial Number to activate my product it says that the serial number is not valid. I chatted with adobe for almost 1 hour and the best thing he could tell was to post my issue in this forum. Wow, it is amazing that this is the way Adobe addresses customers issues. Post it on a forum and see what happens.
