All of a sudden, when ever i try to run the Logitech G25 software a window pops up saying it needs to close and gives me the option of closing it or waiting for it to respond. Iv tried re-installing and its still the same, any ideas ??

What changes were made between the last time it worked and the first time it happened? Did you install any windows updates recently? If that's the case you might be able to go back to the previous restore point and try... Although I don't think I've heard of a Windows update getting in the way of the profiler...

When you tried re-installing the software, did you remove the existing installation first?

Yeh i removed all the software components before re-installing, and no nothing has changed i dont think. I really need get it sorted. i can still use the wheel its just it only turns like 180 degrees and its really annoying as steering is really sensetive

Please post the exact wording of the error message or take a screenshot of it.

According to this it's possible that the "ntdll.dll" library file got somehow damaged or was replaced by another version which LWEMon has a problem with. Are you using the latest version of Logitech drivers? Are you 105 % sure that your computer is virus-free? As a last resort before complete reinstall you can try reinstalling only the latest Service Pack only or if you have a restore point set roll back to an older system state.
