[edit]The new problem is that it tries to use com1 serial port to output[/edit]
I don't understand. "It" probably doesn't mean the sketch, since there are no serial commands there, and the sketch does not use digital pin 0 or 1. Does "it" refer to the Arduino IDE? If so, pull down Tools > Serial Port and select your com10 port before uploading. Com10 will only be available in the list when your Arduino is connected to your computer via the USB cable.
Can you post your operating system and version if that is not the solution?
