When uploading large batches of files it's important to not let your computer go to sleep on you :)Follow these steps if you use Windows Vista.
Click the windows icon lower left, and then click "Control Panel"
Click "Hardware and Sound"
Click "Change power-saving settings"
Click "Change plan settings"
Click the dropdown for "Put the computer to sleep:" and select "Never" and then click "Save changes."
Your're done!
