Query: Great product, but...

Great product. I'm learning how to play chess for the first time, as well as my 7 year old son... However, tech support is not the best - my program gets an error message during the IntelliGym, and can't move forward. I contacted the tech people via e-mail, but it took them nearly two weeks to get back to me. Suggested solution didn't work, and haven't heard back from them yet. Hopefully, you won't have any tech problems, then you'd love the product, I'm sure.(I think my problem might be my OS, which is W2000 - even though the product discription in Amazon states it works with W2000, the CD I have says 95, 98, ME, XP. So W2000 uesrs be aware...)
