Sorry, I should've been a bit clearer & said "delete the preferences folder again"
It's a good idea to delete that folder after updating or upgrading LW

You could also try NT compatibility (even though you have XP) & running as administrator...see that 'fixes' thread in my previous post.

Are you running Windows & Norton firewalls together? Don't...they'll conflict with each other. Turn off the Windows firewall & configure Norton to allow LW.

You're using a wireless adapter...what's the brand & model of the modem/router that you're wirelessly connecting to?

birdy i believe i've configured windows firewall off and norton allowing lw already.. no luck..

how do i look for the specs of my modem/router?

Try reinstalling LW again. You could also try the Beta version & see if that opens (you can download the Beta from your personal download page).

The wireless adapter that you're using doesn't have a firewall. But if you're connecting wirelessly through a router or modem-router, that might have an internal firewall. To check, go to the other computer & see what devices are plugged into that. Maybe another D-Link device?

yes birdy, this pc is connected wirelessly with another D-link device, because cox's cable internet connection is wired from that remote pc.. thanks for bearing with me birdy.. but as another favor, can you tell me how and where i could find that firewall culprit?.. is my d-link a router?.. the remote d-link is a modem-router?..

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)?
