I Can't upload my reports, it tells me "Unable to upload report: report name contains an invalid character! Name must only have letters or numbers"

The file you are trying to upload most likely contains spaces or special characters , thus you are unable to upload the file. To correct this problem, please rename the file and remove any of these special characters (@$%^&*!) and any spaces between the words..i.e. From "your report 2004!" To "yourreport2004"
