It's a timeout. It's a known issue files over 5MB or so have problems with some connections. The slower the speed at home, the more chances for the timeout to affect the upload.
1) Compress the file with rar prior to uploading. Depending on the contents, it may bring file-size down significantly, hence making upload faster so it can avoid the timeout.
2) Upload to any of the freebie file servers, then link it.
3) Send the file as attachment to betselection﹫gmail.com
