When you upload your assignment to LoudCloud, the system will automatically scan your file to make sure that it's virus free. Sometimes, the submission will freeze or take a long time to finish. The most common cause for this is a poor internet connection:

1. Check other websites to make sure your connection is working well or restart your modem to reset your internet connection.
2. Try clearing your cache and cookies or use another browser to upload your file if the modem reset does not resolve the issue.
3. A common way to resolve this issue is to simply copy and paste the entirety of your assignment into a new file of the same type. That means, if you are having trouble uploading a Word document, you can copy and paste your assignment into a new Word document and upload the new file.
