Rys,
I don't know why anything would tell you that it's not a valid VST. The ONLY thing that I can think of is that you are not attempting to select it from the drop down list, but that you are going to 'Load VSTi' and going to the directory where the TTS-1 is located. Don't do that, if you are. The TTS-1 should be in the drop down menu list. Furthermore, the TTS-1 should be left in the Cakewalk directory where it was loaded.

Use the button (I forget which one, I'm not sitting in front of my music computer) that allows you to scan for new plug ins. Once you put the TTS-1 back in the Cakewalk directory, press that button, and it should find the TTS-1, since that is the location it will be registered in. Then, you can select it from the number 1 drop down menu.

DO NOT try to load it as a VSTi, it will not work.

I'm blessed watching God do what He does best. I've had a few rough years, and I'm still not back to where I want to be, but I'm on the way and things are looking far better now than what they were!
