I don't know if there is a limit, but that has happened a couple times as well. If i remember correctly, when it tells you to log in, just hit "back" and try again. It might take a couple tries but it eventually works. Or I just wait an hour and rty again.

 

or just try and upload from cardomain, i found that helps.

 

SD is messing with me too, it wants me to keep logging in, and won't let me upload...oh well. Get what you pay for!

 

Still tring to get pic to upload Still getting LOG ON message

 

log in @ cardomain and try it from there
