The title really says it all. I haven't updated Proun for a few months, so I just simply installed the latest update and couldn't. See. Jack.
In fact, I have a video of me not seeing jack. It starts about two seconds after the game stops loading.

Here are my system specs:

ATI Radeon 4850
AthonII X2 dual core
Windows XP SP 3

Not sure about my sound card, but I'm pretty sure that isn't the issue. And yes, I am fairly certain I have the latest drivers. In fact, as far as I know, the drivers haven't updated since I first played the game. And it ran just fine back then. I also played around with video settings, but those didn't change anything.

Could you send me your Application.log, Ogre.log and Ogre.cfg files, so that I can have a look at what is going wrong here? My email is joost -at- ronimo-games.com.

Some other people reported the same error, but they were using the Battlefield 3 beta drivers and removing those fixed the problem. Apparently you don't have those, so I am curious to know what is going wrong here and to look for a solution!

I think I found it!

The patch as I put it online missed some data, stupid me! I think I fixed it, could you try downloading the patch v109 again and let me know whether it works now?
