Port open / closed

[hangnyon]

I had just started using mtorrent and I checked if my port was forwarded properly, and YES! I was very pleased to see 600kbps downloads. But then I got several times a computer restart with blue screen.

After hours of internetsearches for a possible culprit I uninstalled NVidia NAM and reinstalled the drivers but not NAM this time.

But now my port is no longer forwarded and I get if I'm lucky 20 kbps downloads.

Now I read a lot about routers/portforwarding/static IP address but I don't understand why I am no longer forwarded. Is it NVidia NAM? Do I need that? But that app makes me reboot involuntarily all the time.

Additional problem is I live in Korea, but hell, don't speak the language. I have a modem (no router) Net&Sys MNG-2300 but all I get is Japanese or Korean sites.

Since I was properly forwarded just a few hours ago, can't I get it back somehow without router/modem portforwarding?

On a sidenote: what does this mean?

"located in %AppData%\uTorrent" in the FAQ

Where is %AppData%?!

Thanks

Nvidia is for your graphics, so it has nothing to do with the portfowarding

"Nvidia is for your graphics, so it has nothing to do with the portfowarding"

Eh, NVidia is for my networkcard. Nforce 4 I believe. NAM is Network A.... Management. It comes with a firewall which is giving a lot of people problems. (AMD 64 Processor Mobos with NVidia chipset) (I do have a NVidia graphics card but those 2 are unrelated)

"%AppData%\uTorrent"

But where can I find it on my hd?

Thanks

Edit:

Oh well, I surfed the forum a bit and found this:

http://forum.utorrent.com/viewtopic.php?id=7862

"Rule for TCP/UDP protocol

Action = Allow

Protocol = TCP or UDP

Direction = In

Source IP = Any

Remote IP = your IP adress (or "Any" )

Source port = Any

Remote port = the port your bittorent program uses for the TCP/UDP connections

You must move the rules up, over the default rule "Block IP in". ( CPF "reads/applicates" the rules from the top to the bottom)"

And now I'm connected. Though I do feel a bit unsafe with all those "any". But I don't really understand all that.

BUT one question remains:

"%AppData%\uTorrent"

But where can I find it on my hd?
