I don't know what the problem is with my website(s). I just tried again and it is fine on Internet Explorer, Firefox and Chrome for me. I hate Firefox though, as every time you access a new page on my sites you get a damn pop-up ad that you have to get rid of.
I'll send a message to the webhost via their members area and see if I can find out what's going on.
Software mode is a display mode. Before the LB2 patch and Display Driver Update (DDU) came out, everyone had to run the game in bare-bones Software (DirectX) mode. After the patch and DDU are installed (done for you in my Vista/7 Fix), you get the additional options of Direct3D and 3DFX hardware-accelerated display modes available. Run the 'lb2cfg.exe' file in your LB2 install folder and see what I mean.
