Could not upload file picture.jpg Reason: e:\path\picture.jpg (The system cannot find the path specified). There was maybe 50 error messages which I could not click OK for. I think Wuala should make the error message appear once then stop giving the error. What happened was that after I dragged the folder to Wuala, I deleted the folder. By the time, Wuala got to that queue, the error message appeared.
