Crash and connection help?

[Grimshad]

I couldnt find a tech support area so im posting this here.

I randomly get this error while playing and CTD

---------------------------
Application Crash
---------------------------
Application Crash: EXCEPTION_ACCESS_VIOLATION
shattered_horizon.exe build: 6
gui::do_ui, do_ui, visualizable name:
renderer
do_item_asynchronous_update, item name:
window_painter

Shattered Horizon encountered a fatal error and will be terminated.
---------------------------
OK
---------------------------

Also, when connecting to the 4-5 active servers, i get either "Could not connect to server" or "could not connect, steam authentification failure" 90% of the time.

Any ideas?

EDIT:

add new random crash while loading a map

Try nvidia 195.62 drivers and get latest directx sdk.

Also, do you run a second videocard in your system?
Whenever I try to use my aimbot or wallhack programs I get that error as well.J/k.

No, I only have one card, however, I don't have the latest drivers, so i'll try that.
