Help with reintalling Photoshop, missing four numbers?

[Lina]

Hello everyone, I hope you can help me here.

Photoshop stopped working on my computer, if I tried to open the program, it would start to initialize and check settings and then it would just disappear. I decided that I should uninstall Photoshop and then reinstall it (which may or may not have been a good idea). Before I unistalled Photoshop I wrote down the serial number which was 20 numbers ( I am absolutley positive of this). After I put in the disc to reinstall, it asks for a serial number but it wants 24 numbers...what is going on? Can somebody please help me? Thanks

Adobe is playing games with you. Call them.
It appears they think you are using a version licensed to someone else. They have a fix when you call them.

What do you mean "Adobe is playing games" with me? I am using the same cd that I originally used to install the program years ago.
