Problem with file upload

I have problem with corrupted file. In my f?nix 5s activity is normal, everything seems ok, I can see the distance, time, chart, HR, but this file is impossible to upload in CG, but can upload without any problems in Strava. Try to export from Strava and upload to CG, but this does not worked.And this is second time with corrupted file since last update. Never experienced similar problems with normally recorded activities before this last update.
Is there any way to repair this files and if this is problem with software, it's impossible to predict when file will be ok and when not.
