virtualbox.org

I haven't used VB in a few days, so I started it up tonight and tried to open Windows, and it constantly crashes. It says no error message, but when I display details it gives me this:

Failed to open a session for the virtual machine Windows 7.

No error info.

Result Code: NS_ERROR_CALL_FAILED (0x800706BE)
Component: ProgressProxy
Interface: IProgress {c20238e4-3221-4d3f-8891-81ce92d9f913}

Any ideas?

Thanks

Also it keeps opening in fullscreen mode and I can't figure out how to get it to open in a windowed mode. So any help would be really appreciated
