Such restrictions are really annoying and useless, in my opinion.

I would try following if you have access to your emails or have an email account at work:
Download the patch at home, change the extension or compress it and send it via email to yourself. Then download it at work.
Yeah, always downloaded the file @home and used the only online-Storage I could find which was not blocked (which is also blocked know
)
So yeah, maybe I find another online storage which the filter dont know yet or i'll stick with emailing. ^^
