After reinstalling my operating system I no longer have Photoshop 7 and I "can't live without it" so I'm thinking about downloading the Photoshop CS4 free trial and then paying for it when the 30 or 90 days is up. Does the download save fully to a CD-R so that if you have to reinstall or upgrade your OS you'll not loose the program? How do you pay when the time comes? After you pay do you get a serial # to permanently unlock it or do you have to download another copy?
Also, when using the free trial version, does it put a "Photoshop" water mark on it or anything or is it a full/unaltered version?
