If you're having issues with the file hosting site, with uploading or downloading, please post problems here, for upload describe your issue as detailed as possible, for downloading one thing that will help is giving me the MD5sum of the file you downloaded, for windows users, use www.fastsum.com tool to get the MD5sum, for linux users use the binary 'md5sum' and post the md5sum here so i can compair, i believe it has to do with my firewall filtering, if so ill leave port 81 alone.
