help me about ADS2005A installation!!

hi,everyone
could someone give me some advice about ADS2005A installation problem?

it always appear that "the system time have been setback", why?
and how to solve this problem?

hi]i also need the following installing idea...
please help if anyone knows

After installing the ADS, you cannot change the date of your computer system,
please reinstall your OS, and the install ADS again
\C:
should be formated firstly

y should check your license

It's Absolutely Correct! I got this Problem 2 months ago,and nothing resolved until

installing OS again Completely.(Even Reinstalling ADS2005A or Installing ADS2004A,

Both versions have same Error Message!)

GoodLuck!
