Is there a way to use it in manual mode only, like with an adapter? I paid $30 for shipping and I wouldn't want to lose that. I'll also send Sigma an email.

Not really.  If you set it wide open (f/1.8) in Av or M mode it may work, the miscommunication on those old Sigma lenses is typically related to trying to stop down the aperture.  But being limited to f/1.8 doesn't make it very useful.
