You didn't mention what OS you are using. Lock ups!! What a pain. Try some simple things first.
As far as the Error message goes, that's Greek to me. You might try going to the Microsoft knowlege base or FAQ for the games and see if that error message is listed. If not, try the following steps.
1] Get the latest Direct X which is DX 9.0b
2] Get the latest drivers for your vid and sound cards that are DX compatible.
3] If you are using XP, see if there is a patch out there.
Also, Memory sure could use a boost. These flight sims are very memory intensive. Get as much as you can afford.
Finding the cause of lock ups for us lay people is a hit and miss thing in my opinion. But good luck and keep us posted.
