Err, you have three
anti-virus programs? I see Avast, Bit-Defender and Microsoft Security Essentials. Any one (or a combination of any two, or maybe all three) could interfere with xTrap, you'll need to disable them all and see if LT will run. If so, you can try re-enabling them one by one till you figure out what causes it. But really, 3 anti-virus clients is beyond overkill, it's a recipe for trouble.
This looks suspicious, simply because it's not a normal place for a program to be running from:
O4 - HKCU\..\Run: [GateWay] C:\Documents and Settings\Kris\GateWayMain.exe
If you know what it is, and you know it's legit, that's fine, otherwise I suspect malware of some kind.
Failing that, you'll need to try closing out all the extra programs and stuff. That means stuff like Skype, that Gadu-Gadu program, OpenOffice.org and Opera. Sometimes xTrap can take offense at innocent programs.
If still no luck, try disabling the WinPcap service. Since that's a packet capture thing I could see xTrap possibly disliking it.
O23 - Service: Remote Packet Capture Protocol v.0 (experimental) (rpcapd) - CACE Technologies, Inc. - C:\Program Files\WinPcap\rpcapd.exe
And finally, since it looks like you're running a non-English language version of Windows, check the manual patch & solutions thread
and look at the section about French Windows XP under xTrap errors. It's possible xTrap has developed the same issue on other language versions. I don't know if the same steps will fix it or not, but it's worth a shot.
