Hi I am playing in interlude (c6) server, I have started using this bot, but I can not use it's efficiency as if I am dual boxing, for instance bishop, he will be reacting very slow, it is because for some reason another interlude window gets slower in a background (i have unchecked the background performance thingy in the bot menu). So i decided not to play in a windowed mode but if i change the resolution i get critical error:

2012.5.19 16:17:01
OS : Windows Vista 6.1 (Build: 7601)
CPU : GenuineIntel PentiumPro-class processor @ 2261 MHz with 4095MB RAM
Video : ATI Mobility Radeon HD 5470 (6105)

Error setting display mode: CreateDevice failed (D3DERR_DEVICELOST). Please delete your Option.ini file if this error prevents you from starting the game.

History: SetViewport <- UD3DRenderDevice::Lock <- UViewport::Lock <- UWindowsViewport::Lock <- UGameEngine::Draw <- UWindowsViewport::Repaint <- UWindowsClient::Tick <- ClientTick <- UGameEngine::Tick <- UpdateWorld <- MainLoop

p.s. I don't get critical error like this when i run l2 without bot. I used FAQ's of this forum and downloaded all the programs and etc, but it doesn't seem to help. Any help would be incredibly appreciated. Thanks!
