Cannot export in ardour 3.5
I just installed Ardour 3.5 a few hours ago in Ubuntu studio 12.04. I recorded a track, exported it and it went fine.
Then I had to figure out how to mount an sd card (which is another issue in ubuntu) so that I could export directly to it. Apparently, after I did this, ardour can't export anymore. It just stays stuck on "exporting timespan 1 of 1". A file is created in the folder (on the harddisk) but it doesn't get bigger than a few bytes.
What could be the problem here?
