I bought the Fender Collection 2, which shows as registered under Amplitube 5 in the Product Manager, but I don't see any of the amps in AmpliTube itself. I also don't see any way of downloading the collection in the Product Manager.
Side note: IK's method of registering, downloading and installing software is the most confusing and frustrating of any software - any, bar none - that I have ever used. You need to rethink this and start over.
