I have been using NST relatively frequently the past month and it has worked perfectly all this time, until yesterday. Then I suddenly got a "Check for update fail. Internal service error" message upon start up. I didn't think more about it and did my 20km bike ride. When I attempt to upload this workout to the web (after choosing to share with friends), I get a "Group refresh failed! Error: 0" message. It still allows me to continue with the upload though, and when I select friends again, I get another note stating "Upload of workout failed. Internal service error" (this note is localized and I don't know what the exact English words would be).
I haven't changed any settings since the last workout and the only thing I can think of is that it might be related to the maintenance that was done to the NST site yesterday.
I'm using an E71with sw v.100.07.76 (08-06-2008)
Sportstracker v2.06
