My photoshop8 no longer works after P.C. being in the shop for an anti-virus update. What to do now? Running the old disc again didn't fix it?
Photoshop version 8 is Photoshop CS you may have a problem if it needs some kind of activation. Adobe took down its old activation servers. Adobe also provided a version of CS2 for old users that uses Adobe new Activation servers. However I do not remember reading anything about CS. You may want to do a search about running CS these days for CS is ten years old.
CS no longer can be activated with your old discs and serial number. Adobe has provided a free installer and serial number for Photoshop CS2 which you are entitled to as an owner of CS.
Just download the installer and use the serial number next to it.
