linksys pap2 stoped working can`t open their browser

need urgently help, am already sorry I bought that thing,
it stoped completely working, and into their browser I can also not go anymore, I changed only the browser port and now am offline completely and there is nothing to do.
I guess I even can`t give them back this pap2, I am here and crying and all of my money is gone, I wish I would not buy it ever, I wish I would buy only this usb thingy and thats it.
Can someone help me? Please! What to do to get the webserver port to port 80 back after I did this misstake? How to get in to their website again? It will not load anymore, help.

Hurray, got it back working, could fix the misstake after getting it back to the factory settings from the phone,then I could get into the Web browser again.
