Can't access virtual servers section in router

[o2brew]

I'm using a speedstream 2604 router. I was trying to change some of the port forwarding in the 'virtual servers' section of the router today. I discovered that when I try to access that section of the setup it is freezing up the router. I have to unplug/replug the power on the router to gain network/internet access again. It never lets me into the settings. I've tried this with both mozilland and IE, with and without antivirus and zonealarm running. All the same results. I hadn't tried going into virtual servers for quite some time, several months. It used to work fine, now suddenly it doesn't work at all. Other than this the router works fine, I can access all other features and didn't realize there was a problem until I tried to change some settings there.

Any clue what the problem might be? I didn't see an option to set the router back to factory default settings or I would have tried this too. If there is such an option on this router to do that where is it? Is the router dying or what?

#1)Is there in you manual a way to reset your router ?
#2)Have you updated the firmware ?

It's running the lastest firmware. Listed as 1.1 Release 05 in router settings. 1.0 Release 05 is latest listed for the router. This is normal from what I've read.
I don't know of any way to manually reset the settings.

Ok, there should be a reset button on the bottom. Unplug it and then press and hold the reset button and power the router back on and release the button after~5 seconds.

Mucho thanks amdfanboy. That did the trick. Now that I think about it I think I remember reading that holding the reset button for 5 seconds was supposed to reset back to default settings. Totally escaped my train of thought though.
