Error shorting a stock..please help

[sportstrader]

I am semi-new to investing with about one year of trading stocks and options. Up until now I have only first bought and then sold.

Now Ive found a company which I think is a trainwreck waiting to happen and I want to short their stock listed on nasdaq. I tried selling 1 share of theirs to test it out but got the following error message [ QUOTE ]
The stock you marked forshort sale is not presentlyavailable to borrow and/or
it is on the Reg SHO list of securitiesrestricted from short selling. You may not sell this stock shortthrough the IB system.

If you have an idea what this is, can you advise me on what is wrong here and how would I go about short selling the stock. I should note that I looked and this company doesn't any options available for trading so buying puts or selling calls is not an possible.

Please excuse my ignorance and help.Thanks
