I have a registered copy of Guitar Combos ACID edition that was included with Acid Pro 7. It has recently started crashing -- all three amps, regardless of whether i use them as VSTs in a host (Reaper) or as the standalones. The symptom is that they launch and then seem to lock up before any interface appears. I've tried uninstalling, reinstalling, running installer as administrator, etc etc. At this point my Service Center shows an authorized copy of Combos but also shows individual entries for the three amps that show as not authorized, and I have no idea why. Is anyone Guitar Combos on Windows 10 64 bit? Am I just hitting an incompatibility? If so... I have quite a lot of past projects that make use of this plugin that I now can't load. I found the .bnk files for the original presets. I have Rig 5 Factory Selection, but cannot seem to make use of the presets I downloaded. I've ordered Guitar Rig 5 as an upgrade from Combos, but it apparently requires manual approval so I am waiting. My assumption is that with the full Rig I will be able to use those presets to at least get the projects to sound the same. Correct?
