Okay Nate, finally got around to running what you said. Results took longer this time, and it worked, I think?
processed file: C:\Program Files (x86)\Spine
Sucessfully processed 1 files; Failed processing 0 files
What does that mean I need to do? Cause I already previously tried running Spine as an administrator
Okay, so I just tried what Mnemonic suggested, and it finally worked! Thank you very much, to all of you (especially Nate and Shiu for working with me for so long).
