[1.62]Editor does not work

[Bravo_Two_Zeroq 10]

Since beta patch 94945 the editor no longer works. I have about 40% of all units and vehicles available to me. I can edit a mission with these units, but as soon as I try to load I get a DirectX 9 error and screen stays in middle of map. I can play every other mission just fine as well as multiplayer, just not the editor.

Is it a problem with 1.62 RC or did some of the beta patches screw up my editor installation and do I have to go for a reinstall?
