Hi All
For the first time I have had the dreaded Error: "...user name, organization, or serial number is missing or invalid..." when you start Photoshop This is CS2.
Now I recently had a problem with ZoneAlarm Free conflicting with my Kaspersky AV - I have since removed as per directions ZA and upgraded the KAV to Kaspersky Internet Security.
Having sorted this out I now get the CS2 error message....agh!!!
I know from seeing this mentioned elsewhere that this happens but for the life of me I have no idea what caused it in my case because as I understand it the error means the CS2 registration key in the registry has been removed or damaged & nothing I did IMO should have affected or influenced 'that key'.
I would welcome any pointers/links and guidance on this one.
TIA
