That's a really strange issue. Never seen or heard it before. There may be a problem with your server's version of Perl and the Uber Uploader program. I would suggest that you download the latest version and try that. One thing to note is that the version that comes with vShare states that it is 6.7. However, this is an error (as there is no version 6.7, the latest is 6.5). Rather, it's version 5.3.6.
