I, too, am having problems with this.

I was originally running an older version fine, until one day I decided I'd finally listen to the pop-up and download the new one.

I did so, and haven't been able to use it since.

It starts up, and I see the logo for a few and opens up. However, it's just a slate of grey.
When I hover my mouse over the search box, it blinks, and I can enter something, but that's it.

Here's a pic of it:

I've had to resort to Ares to share (vomit).

Please help me out...
I know you're gonna say it's probably the XP theme I got, but it's not, because this problem was in effect before I acquired the theme.

And since you asked, here's my info on my comp:
Dell, Intel P4 w/ HT 3.0GHz
WinXP Pro
1024MB DDR2 SDRAM
Limewire 4.8.1
Java version unknown (don't know where to check nor where to update... that might be the problem)
Firewalls: Microsoft AntiSpyware, McAfee Personal Firewall Plus (both installed AFTER I got this problem)
Connection is DSL
I'm connecting from home
I'm using Verizon DSL

The questions I skipped I either don't know or didn't answer because they're not relevant.

Thanks for your help.
