Why do I keep getting a error when I upload a file/PDF?

If you continue to get errors when you try to upload a file please rename the file making sure it contains no symbols. Some symbols can confuse the system when uploading. For instance if you file is named #1times&entries.pdf.  The # and the ampersand (&) will cause this error. We suggest naming it number1timesandentries.pdf.  Another common symbol that will give you an error is the % sign.  

Also please note if you are placing a file in the editor it cannot be larger than 10MB and will give you an error.
