I just read at Daz3d forum that Adobe have provided downloadable files and serial numbers for Adobe CS2 for what appears free. I'm not really sure what's going on but following is link to Daz3D forum on the subject. They also have the link to Adobe site where CS2 files and serial number is located.

I have CS1 and I don't think I'll bother to get CS2 (it's 4GB!!!). It's only 32bit anyway and I'm already saving up for Photoshop CS6 Extended 64bit.
