Can anyone help.....

Been trying to upload my mix using mediafire and when my file has been getting to around 10% i recieve an error message and the file stops uploading.

This is what it says - "The identifier you are using is invalid. This could be a Javascript problem with your computer, ensure you are allowing javascript to run fully for the Mediafire.com domain. If this problem persists please contact support directly"


Any help much appreciated... as i want to get my mix up for you lot lol
