2.1.1 ACCESS TO ANY OUTPUT FILES CREATED WITH THE SOFTWARE USED ON A TRYOUT OR TRIAL BASIS IS ENTIRELY AT YOUR OWN RISK.
A bit worrying. I'm wary about forking out for CS4 without a substantial tryout on my book files, unless I know definitely that it does a better job than CS in specific areas. Does 2.1.1 mean that the trial version is crippled in some way? That files worked on during the trial period won't open afterwards, even with a full version? Has anyone had problems opening or printing files generated in a trial version, either during the trial period or afterwards?
I think what you are reading is boilerplate created by lawyers to protect Adobe from lawsuits from people who haven't paid for the program.
Fact is, trial versions don't get any support. So that's the lawyers way of saying "bug off." (Original phrase edited.)
But I don't think you will have a problem.
However, you do know that if you convert your file to CS4 and then do work on it, CS will not be able to open it.
That section of the EULA is a CYA clause. You're using the trial at your
own risk and if you can't do anything with the files when you're done
that's your problem.
PLEASE WORK ON COPIES OF YOUR FILES!
CS4 files cannot be opened in CS and even if you went through the CS4 to
CS3 to CS2 to CS INX process I doubt you'd be at all pleased with the
results.
