sometimes the tuelz load ok

sometimes i get this error in firefox

"Firefox can't establish a connection to the server at 127.0.0.1:12345.

Though the site seems valid, the browser was unable to establish a connection.

* Could the site be temporarily unavailable? Try again later."

I turned off the firewall and that did not help.

yesterday I re-booted and then it worked, but today no such luck.

using win xp pro with sp 3

Yesterday when tuelzBS99 did open INZ was not on the list of programs.
I tried to open INZ by clicking on it and that did not work.
Windows sees the .mod extention as a video file, I changed properties to have the .mod open with tuelz.

anyone have this kind of thing happen just sometimes not other times?
What else can I check?

Using Tredn micro PC-Cillian 2007 and wondering if that could effect tuelz somehow
