Yes. I also have the same issue. I believe I have a free sample tank 4 (not 100% sure though). I have directed sample tank to the sample tank folder that has the SpacePort install files. However, Sample Tank has scanned the folders. But nothing shows up in sample tank about the spaceport.
I am on windows 10.
