A single can not be more than 500MB (to provide bigger files, use our
external hosting feature). Also, make sure that you have enough free disk space in your E-junkie account by goign to E-junkie Seller Admin > View Summary.
To ensure that your anti-virus or firewall or any other internet security software is not interfering with the upload, please disable those while you are uploading the file.
This issue can also be related to your browser and if you are constantly having this issue, try a different browser.
Another thing to make sure of is that you DO NOT close the main browser window in which you have E-junkie seller admin open, as that will log you out and your file upload will fail.
