I cant delete techdemo! HELP!

I was thinking about buying Beamng.drive, but I wanted to test if it would run at a decent frame rate before i spent $20 on it. When I down loaded the demo it said i downloaded it incorrectly, but i cant delete it to re-try.
(see image to see what i get when trying to delete it)

 

Looks like you tried to delete it, in the way of pressing "delete" on the keyboard. It seems like it mostly is gone, but some small things are remaining due to a wrong removal. Try to go into control panel, and see if you can find it there. If not, then it is gone most likely.

 

ok thank you!
