Hey, so i got this CS4 photoshop on my win 7 64 bit computer and i have the following problems:
1) On opening, it asks for a valid Serial, even though i have one and i have to enter it each time
2) the DXT tools do not work (invalid file when trying to open after i have installed them)

If you paid this 1200€ for photoshop then your serial should work.
You said you have a legal version. Adobe have a support use it.
Renegadeskins.net isnt a support site for Adobe products.

If you dont have a legal version contact me @ msn.

I still cant get it working even with a file cysis sent me :/
