Has anyone else have a problem with HeiaHeia uploading?

I am using version 1.66. The HeiaHeia upload worked the first time used it, I uploaded several files (5 or so).
After this I quit the application, transferred more .gpx files to my phone and started eCoach again. I tried to upload these gps files to HeiaHeia, but now it always says "Uploading to HeiaHeia failed!"

I am using HeiaHeia via my facebook-accont.

I have reset the upload settings, i have removed the app from my facebook-account and logged out manually from both HeiaHeia and facebook on the phone browser. I have uninstalled eCoach and reinstalled it. Nothing works, the upload has never worked again after the first time.

I realize there is a new version on the works, but I was wondering if anyone has had a similar problem and maybe a solution for this version?
