Exception raised when setting reference frame

I was trying to use a FITS file created by pixinsight (tried 16 and 32 bit FITS) to set up a reference frame for a target.

When I click the solve button after entering the scale, it looks like things are about to work but then get an unhandled exception and SGPro quits. This does work with a PNG file.

Here are the details:

Parameter is not valid.

Thanks for the report. This issue had been found and fixed here:

Will be out in the next beta.

Thanks,
