Pro Tools will typically close after this error and return you to your desktop with no further errors.

Here are some things to check:

Make sure if you have previously installed ProToolsFree that you uninstall it before installing ProToolsLE.

Check to see if you have installed any third-party plugins other than what came with Pro Tools.

It could be a possible chipset incompatability with your motherboard. Check for compatibility at digidesign.com
