    Please answer all questions.
    We want to help our users.

    The opengl error message is often displayed when your PC does not meet the requirements of the Cubism Editor.
    In rare cases, you may see it even if your graphics board driver is old.
    If you ask us questions without any information about the PC environment you are using, we have nothing to judge.
    Please understand.

    this error is because your graphic cards is too old or either your pc/laptop requirements doesn't support the minimum ones. i've also had this problem for over 4 months and it is really sad cause we don't really have nothing to do about this problem until i ended up using 2.1 version wish is already ended support :(
    i just really wish they'do a version for low end pcs.
