It looks like my data is gone. I found the TFlog.csv in my TF main folder. I can open in with works (I don't have excel). When I open it I can see the column headers for miles, time, etc but there is no data there.
I suspect my problem has nothing to do with Topofusion. My virus checker picked up a bunch of stuff in a scan today... No biggie, I can recreate what I lost since I've still got all the actual gpx files.
One feature I think would be kind of cool would be to have custom fields in the activity drop down menu. In my case I would like to spec which bike I used for each ride. Then I could easily sort data according to each bike and know for instance how many hours riding time I have on a shock since it was last serviced. Kind of anal, I know. Thanks for your help.
