I currently have cs, i upgraded to Illustraor CS4 but upon installation, it is not excepting my serial number. I had to use a trail. Customer Service is of course closed. Does anyone know what I can do?
Wait till tomorrow!
yep, that is the level of service and performance you will get from Illustrator Team.
Do you know that Adobe knows that there are problems with its installers, but Adobe still refuses to provided updates. I can almost guarantee you that Adobe will blame your OS. (John Nack, Principal Product Manager, Adobe Photoshop, said it: http://blogs.adobe.com/jnack/2008/12/notes_from_installer_mgmt.html#more)
Adobe is not providing updates for illustrator since 09/04/2007 (ALMOST 3 YEARS AGO!). I really do not know why still selling a bad software.
Maybe tomorrow you can ask them why?
