[19:13:49] EXCEPTION_ACCESS_VIOLATION (0xC0000005, 0x00000000, 0x3A4CACBC)
This will most likely be fixed by disabling DEP which is a windows security feature designed to prevent programs from accessing shit they aren't supposed to. As a fellow crpg player I am assuming you don't care about PC security and just want to play the vidya. This is how you disable it.
1. Type
cmd in the start search menu,
right-click on it and select Run as Administrator.
2. Once the command prompt is open, you can now disable the DEP by entering the following command line.
bcdedit.exe /set nx AlwaysOffReboot after this and try playing crpg
3. And to enable it back if you want it back or if this doesn't work,
bcdedit.exe /set nx AlwaysOn
OR, if you don't want to disable it completely and want to try to just disable it for crpg
Right click on your "computer" --> Properties --> Advanced system settings --> Advanced tab --> click the Settings... under the performance catagory --> "Data execution Prevention" tab. --> select "turn on DEP for all programs and services except those I select:" --> Add... --> find crpg_beta.exe which is in your Mount&Blade Warband directory --> Apply and reboot then you should be done.
