Using the old TS 4.0 studies and systems in newer versions.

[murpran@xxxxxxxxxxxxx]

Hi All:

Is there any upward compatibility with the old 4.0 studies and systems
in the newer versions of TS. If so, which ones are still available that
will run them. I can't seem to get my old 4.0 to run on this new
machine. 

Thanks,
