0AD no longer loads on my PC. It did yesterday so what's changed?

[Tom]

0AD stopped working yesterday and so I reinstalled it and it seemed fine. However it's back to not working today and reinstalling isn't helping.

I get this error message as it crashes out upon loading:

Much to our regret we must report the program has encountered an error.

Please let us know at ​http://trac.wildfiregames.com/ and attach the crashlog.txt and crashlog.dmp files.

Details: unhandled exception (Access violation reading 0x00000000)

Location: unknown:0 (?)

Call stack:

(error while dumping stack: No stack frames found) errno = 0 (No error reported here) OS error = 0 (no error code was set)

The textual crash dump doesn't contain any useful information.

• Try disabling all graphics options, especially GLSL
• Try windowed mode rather than fullscreen (it likes to crash when doing alt+tab)
• Maybe directory permissions changed (for instance when doing a windows upgrade) ​http://trac.wildfiregames.com/wiki/GameDataPaths
• Some anti-virus software restricts 0AD for no reason

If that doesn't help, someone would have to look at the dmp file on windows. Or you can try to download alpha 23 preview by installing tortoise svn to download the daily updated development code: ​https://trac.wildfiregames.com/wiki/BuildInstructions

Hey Tom, thanks for the report

The issue you are encountering is linked to your soundcard, if you have disabled it, or are using an external soundcard it might break. That bug is fixed in the next version. in the mean time look at your sound settings.

Regards Stan

I'm closing this issue as Needsinfo, feel free to reopen it if the above solution does not fix it.
