Upgrade from CS3 to CS4 Extended

Posted By

I have just purchased an upgrade from Photoshop CS3 Standard to Photoshop CS4 Extended, and have problems activating. In the dropdown it only offers an upgrade from CS3 Extended and will not accept a serial number from CS3. I’ve spent about 2 FRUSTRATING hours on the phone today and all they can offer is that I give them the challenge code and they activate this installation, and each time I have to re install I would have to do the same. Needless to say I wasn’t impressed at all, and have got an RMA number. Has anyone else suffered from this problem?
