OpenBCI GUI a Blank Screen

edited August 2016 in OpenBCI_GUI
Just received my 8-bit OPenBCI, but having a hard time just getting off the ground.

The OpenBCI GUI opens, but is a blank screen. Running Windows 7 64-bit.

I followed precisely these directions: http://docs.openbci.com/tutorials/01-GettingStarted

I read through and found no resolution in:

If anyone has some ideas, I'd appreciate it.

    This page suggests checking your graphics driver(s). They need to be compatible with the latest OpenGL,

    That did the trick!

    I have a Dell Inspiron 14z with Intel HD Graphics 3000. Just needed to head to intel and get the latest driver, ran no problem.

    I do get an extensive list of java exceptions when I start it though. I will investigate this further:

    Found this supposed fix for the Exception you mention:

    i found myself the answer changing the authorizations for the libraries folder to "everyone reading & writing" and now p5 2.0b7 launches ok
    but i cannot understand why i had to do that ,as 1.5.1 runs without this change....
    i have seen that others users have the same problem
    hoping that it helps them!
    ph c.

    From comments on this page:  http://www.learningprocessing.com/tutorials/libraries/

    That reference addresses the same exception type (NullPointerException), but at a completely different portion of the code.

    I downloaded and implemented this "Processing Debugger" to try to identify the source of the issue: http://debug.martinleopold.com/

    Crazy enough, the problem does not occur with the debugger mode enabled...

    I'm also having this problem on a Win7.1 64b Dell Inspiron machine with latest video drivers.
    Getting a blank window when sketch is run with no warning / errors.

    Please help!

    This problem solved - the issue was old graphic drivers. With their update to recent ones (6/15) proper functioning was  restored.
