More information please, are you on a windows domain? Is group policy in effect, most likely, have you tried disconnecting from the network, and login using the local administrator?
If the local administrator is disabled, theres always this little trick you can do, but I guarantee either your proxy or WanOP device is blocking traffic to EQEMU, unless you have a stupid IT department, or work for a small company where bandwith isnt a problem.
Try this, if you're not techinically inclined, this shit is fucking cake.

Dont ask me for help, because I'm not your IT support.
Note:Modifying anything on the machine outside of the IT department qualifies for immediate termination, in the many company's I've worked for.
Dude, I don't take responsibility if you get fired for wanting to slack off at work, you shouldn't really have downtime, and should keep yourself busy, if you have free time at work, you're not working, just saying.
Good luck, and I hope you aren't standing in the unemployment line next week.
