Bad times got worse at Atari ( ATAR ) as the company posted a loss and a 35% decline in sales in the important holiday quarter. The struggling video game publisher also announced that CFO Diane Baker has resigned, effective immediately, to "pursue a new opportunity." And if that wasn't enough, the company said that HSBC, a bank that has provided it with working capital, has cut off the company's credit line. Atari warned last month that its holiday quarter results didn't meet the strictures the bank put on the company last year. "The uncertainties caused by these conditions raise substantial doubt about Atari's ability to continue as a going concern," the company said in a statement. Investors reacted accordingly, dumping the stock in after-hours exchanges. In recent trading, shares of Atari were off 32 cents, or 36%, to 56 cents. Certainly, the company's results in its fiscal third quarter didn't give investors any solace.
