Stay in school, kids.

How cold was it outside?

Your laser is probably DPSS (Diode pumped solid state). DPSS lasers don't function very well in cold temperatures. Just warm your laser up before you use it.

Correct me if i'm wrong on this stuff.

Also, introduce yourself in the welcome section and add your location. Most people would be more willing to help you with other problems if you do this.
