Is there the yellow BC cursor?
If there is, then get us a console report.
Otherwise, have you tried pressing "Enter".
Or if that didn't work, try Alt+Tab untill you see a BC icon, go there, and take a screenshot of that (and post it here after you saved it as an image in Paint).
And if that failed, make sure that you aren't attempting to run 2 BC's side by side, that won't work.
