everytime before you start PS CS----Troublesome but useful
Since the version you download is the crack of PS CS pre-release(installer nearly 200mb). it was automatically set 2004-02-12 as the expired date, so far no cracker can break that.
If you are lucky you can try to download the full version(298mb).The with the cracker, you can save the trouble of changing date everytime.
But seems there are not too many differneces between these two version.(At least I have not heard any).
BTW, I am now using PS CS (pre-release)+PS 7, happily.
