Router help

[DanMc07]

Hey I am having trouble saving settings in my router. My router is a BEFSR41 v3
I can log into it fine with the admin user and pass, but when it comes to saving it, it always prompts me for the password, I fill it in, and then it tells me it is incorrect.
Now I know it isn't incorrect as I had to just log into the router with that user and pass
anyone else had this? And if so how do i fix this problem.. As I need to open ports in which it wont save.

Hmmm... It seems to be the Firefox 2.0 final browser.
Just tried it in IE7 final and it saves fine..
Strange

EDIT:

No it isn't working again.
It lets me save them. But it won't let me enable them.
For some reason it let me save my uTorrent port but not my port for my game. (Madden NFL 07)

After further inspection it seems that it only wants to save 1 entry. I restored it to factory default. and it only saves the first entry without any trouble. When I try to add the 2nd,3rd etc thats where the trouble starts??
Any ideas..

NEVER MIND: Fixed it. Got in touch with tech support, they sorted it out.
