I had a bit of an epic struggle with CSR and a couple of other things I bought while back - essentially I wound up having to pretend I bought one product and the upgrade to the thing I actually ought - then when the compulsory "upgrade" to custard Shop came along, it broke most of my stuff & it took folks on here and GS to get me sort of working. IKMM support were less than helpful, which is why I am now very wary of their software. For a long time the only way I could get the products I had bought to work in reaper was to ALWAYS run in Admin mode. Nasty.
And of course with this latest little go-around I am finally convinced they ARE out to get me.
