First, sorry for the double posting above. I hit "refresh" on my original reply when I went back online hours later.
Have you tried downloading a "slowstart" patch for your faster computer? Also, you may wish todownload the UFT 2.8 upgrade after you get your data links straightened out.
It sounds like you may not have gotten a full backup when you went to the faster computer in addition to whatever individual linking problems you may have. The first thing you may wish to do if you still have your old computer is to re-read the section on backups and try again from that point forward.
Your backup file should be in the format *.sqz, not *.pro.
