Mediaportal won't start after extensions update (1 Viewer)

[Makaveli]

I updated MP-TVSeries, PowerScheduler++ and Titan Extended with the MP Extensions Manager. After that, Mediaportal didn't start anymore. The only error I get is: Generic Application Error.
And I should start MP with debug logging, but that doesn't provide anymore information. Logs are attached.

BTW, I already tried disabling the above extensions, but to no avail. Also running in debug mode, did not work.
Furthermore, I re-installed MP. Logs are attached. How can I fix this without a proper error?
This is a pretty new install of Windows 7 64-bit with 12GB of RAM. Before updating, MP did run correctly.

Edit: I did some extra tests, and now I can get it to run, but not on the third display. First and second display show no problems.

The error log shows:

2013-05-23 15:26:53.238521 [ERROR][MPMain(1)]: D3D: Exception: Generic application error. Enable
debug output for detailed information.

This is GPU related.
Have you tried updating to MP 1.4 pre-release?
@Scythe42 did a lot of work on the related code, so you may find the problem is solved... or you will at least get better support.

I didn't install 1.4. Partly because it is a pre-release and this is the main MP machine. But unfortunately after uninstalling and reinstalling MP completely, the PC crashed. This happened when scanning for analog channels on a Hauppauge HVR-2200 (something with paging in a nonpaged area BSOD). After that the whole PC wouldn't start up correctly anymore. So I'm reinstalling and hopefully salvage all the data.
