problems uploading files

So, for the last 20 minutes, I have been trying to upload our latest version of the Animatic. So far though, I have had no success. The file is 15MB and everything only allows me to upload 10MB. I've tried compressing it using .zip and .rar, but it only lets reduces the file size by 0.1MB so I'm still over the 10 limit. Does anyone have any suggestions that could help me?
