Most unusual as the points are always saved for future assignment even if you forget to push the check mark button.

If using Vista / Win 7, there can be some problems with disk writes if you did not install by right clicking the setup.exe and clicking "Run as an administrator" from the resulting dialog when installing the game.

If you have not right clicked the game shortcut, clicked Properties, Compatibility tab, and check marked "Run this program as an administrator", you should do this also.

It is also recommended to turn UAC off during the install and, especially for Win 7 64, install in a directory outside of Program files i.e. C:\Games.

Not doing any of the above can cause the game to be partially blocked from writing to disk. If you did all of this, try making the div.exe a trusted program in your firewall.

Ignore the above if you are using XP.

Also, I use RunFirst to set core affinity to a single core. (Ignore this if you are using a single core CPU) This usually fixes a sound glitch but on some systems just makes the game run better.

If you are using a dual core AMD CPU, you might get some benefits from the AMD Dual Core Optimizer. This stopped some Painkiller jitters on my laptop.

Hope this helps . . . =)
