Sounds like my experience. We finally put TT on a newer computer and it worked. We were able to email the file with the mostly finished return from the computer with issues to the newer one, and open it and finish our taxes. Because I'd been able to save and open TT and have it update a few times before I got the 630 error, I think it was an update to TT that caused the issue with older computers.
If your newer computer doesn't have a CD reader, you can use the online download like we did. However, in order to get that free, we did have to contact customer service. Definitely do this by following the steps on TT under error 630 and hopefully get tech help on your first call. That was the best person of the 3 I talked to. Ask for download if you have another computer it as soon as you can in your conversation with customer service. It's NOT the CD; I couldn't use the downloaded version on mine either.
It was very frustrating that they would not give me a higher level tech service person. Their own site says to contact tech service if you have this issue. Next year I may use the online version as they gave me that finally, but I would have had to start over, so transferring it to another computer was great. Or I'll use our newer computer, but my hubby usually is using it for business. could have an issue with it next year!
Maybe it will help for you to tell TT someone had a similar experience and how it was resolved?
