lejos .bin "open with" problem

I accidentally set my ".bin" file to open with TextPad, instead of the windows default. How do I reset it back the way it was. I believe this is causing an error with my lejosdl. I had everything working with the robot before I did this.

This is the Error Message I get:

C:\394robotics\javaprojects>lejosdl HelloWorldNSK.bin

VM file size is 24272

Error opening Java file: File open/handling error

Please help me.

Thank You
