I'm not able to play!

First thing to do: check if you've got any settings higher than strictly neccesary: for example you could try running the campaign without sheadows, without high resolution (try 640*480), without higher colordepths (try 16bit). The point of this is to find out if the problem lies with your PC or EB build. Then, if you've got it working you can start adding more and more GFX flavour to it; if you didn't get it sorted out:

You could check the Install Guide, and look for the "MD5 Checksum" bit - use the hyperlink for further information. Then you can at least check if your download is corrupted. However, a corrupted install is the thing we blame all weird errors that happen with just one or a few individuals and that can't be explained - weird script errors, such as missing lines etc.

You could run normal RTW (Vanilla) and go to Options. Watch for a version number - it must be 1.5 or EB will not work. In that case uninstall EB; and patch RTW to 1.5. Then install EB again.

If Vanilla said it was 1.5, then you should just try to reinstall EB 0.81aV2 and if the problem persists, you could post your PC specs. There are multiple ways to obtain the figures, one way is to hit start > run > type: dxdiag > press enter > read the various pages with system data. Important: RAM, GFX card; CPU speed (and if it is a dual core or not). In that order.
