Help fixing Garmin activity? Can't load fit file fixer.

Hi, I did 2 rides yesterday, The last ride saved and uploaded fine from my Edge 520, the first one is corrupt.  Iv'e been having this problem with corrupt file's on and off randomly

I tried online fixes and downloaded the fit file fixer, but can't import the file without an error.

Can anyone who knows the program better than me give me a hand?

THANKS! Dave
