Arduino pro and bluetooth mate gold. Not working

Hi.

I have an arduino pro 5V and a bluetooth mate gold. I have communicated with it with my pc and phone before, but now it does not work. The Stat led blinks red with different delay between the blinks. But sometimes when the bluetooth mate gold is connected, it makes the led on pin 13 to blink, and it looks like the arduino resets. I have no idea why this happens.

But now, i cannot communicate with it at all. It just blinks. I cant even find it when i search for it. Has it died? And why does it make the arduino reset?

Sorry for my bad/confusing english.

Hope you can help me out.

Best regards,

The Crusher

Any ideas?
