Just did a clean install of WOTR, patched to 1.21 and installed DX9. When I launch a quick mission or quick combat I get and exception error. When I click OK, the program closes.
I uninstalled and went through the steps again, same result. Did a second uninstall, did it through the toolbox this time, not through control panel like the first time. reinstall/patch/DX9 install. Same problem, it occurs at the "runtime" stage of setting up the scenario. (sorry for blurry pic).
