The D-Link Airplus G DWL-G510 is a wireless adapter & it allows your computer to connect to a modem/router for access to the internet. The adapter that you have in your PC doesn't have a firewall so that's not the culprit.

Is the other computer with the other D-Link device in another room? Can you go & have a look at it & give me the model number? Then I'll be able to tell you if it has an internal firewall.

Did you try reinstalling LW & if so, does it open now?

tried reinstalling the lw beta version, still no luck.. but before i did that, i didn't delete the lw pro.. if a window asked me there's an old version, i just clicked 'ignore'.. wonder if i did the right thing, or should i delete all lw files before reinstalling?..

the modem from the other computer (in another room) is Motorola SM56 speakerphone modem..

what do you think?..

You should let the installer remove the previous LW version. Go to start > all programs > limewire & use the uninstall option from there to remove the LW versions you have now. Don't try to uninstall through add/remove programs, that will cause problems.

Now reinstall LW.

That modem sounds like an internal modem (inside the computer). Are there any external devices (outside the computer)?

i uninstalled lw already, tried to reinstall but can't because there's a running version accordingly.. .. umm birdy, i still saw some program files in my hard disk (executable jar files, etc about 21MB size) that i can't delete because it says lw is running, but i don't see any lw software open or running in my system..

the motorola modem is located outside the computer, so i guess it's an external modem..

do you think things will be normal if i use internet explorer browser instead?
