I'm not sure if you can help me, but I thought I'd try here first. I have a one-year educational license for ADT2006. I just installed it back in April. My computer crashed right before the end of the semester. Due to time crunch I installed the program on my laptop, but never activated the product, uninstalled it during the 30 days. My question is now that I have reformatted and rebuilt my desktop, will I be able to install my educational version again and activate it? I know that if I change the system clock on my computer it will cause problems, but I didn't know if this would cause problems. Thanks for any advice.
