Hello and welcome to the forum.
I am sorry to hear about the problems you are running into. SampleTank 2 and AmpliTube 2 are 32-bit plug-ins (and I cannot remember what plug-in formats they use). Could that be the problem?
Do that standalone programs for those products load and run OK?
As this is primarily a user to user forum, someone-else may chime in [#]. Meanwhile, the best thing to do is raise a
Support Ticket, here for some one to one investigation and help (US (East Coast) Business hours, generally). Response time is usually within 2 working days, but in the current circumstances please cut them some slack.
[#] But please remember that the same symptoms do not necessarily mean the same problem.
