Unable to successfully download paid sheetcam

Attempted a few times to download sheetcam. Paid for it and kept searching emails. Was in spam folder. Clicked it and I got a “token has expired”. Called and emailed tried it again. This time it said " Token has been used". Desperately need to successfully download sheetcam. Definitely an old rookie just trying to get the software. Langmuir has been great but still haven’t been successful.

Are you talking about downloading the license file or SheetCam itself?
