If the money is not needed at the moment, I would hang on and hope that they come up with some kind of restructuring plan.
I was in a similar situation to you, where my shares in Com Dev International (TSE:CDV) were purchased at $7.45, and then dropped to $1.80. I was crapping my pants because the company was losing major money, and I thought they would go out of business.
BUT, I said the hell with it, and just held on. Since then, the company has turned itself around, and the stock sits at $4.03 as we speak.
Good luck!
