I'm not sure as to the cause of your problem, but I've run into this type of issue before.

What almost always works for me is copying in the table files from our office network. In your case that would be the QRTAJ*.QRW files from your \QRASP folder.

Take copies of any files that would be overwritten, just in case.

On the rare cases when that hasn't worked, I've sendt the client's qrtables.ini file to Softrak tech support who can check for any configuration problems.
