I am using the free version of CursorFX. All I tried to do was upload the cursor I made, but I got an error saying that it needed to be in CurthemeXP format, so I tried to open it with the theme editor and save it as a .curthemexp file, but it gave me an error saying it can load both CurthemeXP and CursorFX files, but it can't save them as CurthemeXP files. My second problem is that my theme was showing up just fine before I attempted the upload, but now it's gone. I checked and the actual file for the theme is still there, it's just not showing up in the My Cursors menu for whatever reason. Fortunately, my cursor theme still works, I just can't select it anymore.
