Im on winows 10 i tried the win-32 file but that didnt work and yes i tried the itch app and how do i do the executable via command line
Actually, if you have the itch app installed, try this:
Open the MewnBase page in the app. You should see the red "Launch" button, "Uninstall" options etc on the right side of the screen.
Near the bottom one of the buttons should say "Version 0.30 (mewnbase-win32.zip)" -- Right click on that, should open a little context menu -> Advanced -> View Logs...
Email me the contents to email@example.com - and I'll take a look asap to see what might be going on.
Thanks! Main symptom of the issue looks like it's here, near the bottom of that log file:
err: Exception in thread "LWJGL Application" com.badlogic.gdx.utils.GdxRuntimeException: OpenGL is not supported by the video driver.
[2017-01-23 @ 15:24:10.262] [tasks/launch/native] err: at com.badlogic.gdx.backends.lwjgl.LwjglGraphics.createDisplayPixelFormat(LwjglGraphics.java:322)
A quick search recommends a couple things:
Try just giving your machine a reboot, and run the game again.
Try updating your video card drivers in Windows.
There's also a few posts on StackOverflow that suggest allowing the game to run in SoftwareOpenGL mode - In a couple hours, I can put that into a quick build and email it over to you so you can see if it works for you.
