I just had to do a re-install with Giga 3.0 and patch with 3.04 per Tascam tech support. Now when I try to load old performances, I get a message saying ".gsp performance is a pre-release performance. This is no longer a valid file. " Am I to understand that all my old performances are no longer usable. If someone knows how to recover these old performances, I would appreciate any help. Thanks.
