i have been running the arduino for a while now i was doing different programs for a while at the beginning and then i was using the same one for about 2 months now and i went to change the program and the progress bar for uploading would just stop at the end so i unplugged it and plugged it back in then tried to upload and now it says failed to upload every time i tried so i updated from 1.6.3 to 1.6.5 and im still having the same problem. i tried to hit the rest button but it didn't help.
Can you post either the specific error, or a verbose log of an attempted upload. This will, hopefully, give us a better idea of what is happening.
sorry, yes i can,
Arduino: 1.6.5 (Windows 8.1), Board: "Arduino Uno"
Sketch uses 450 bytes (1%) of program storage space. Maximum is 32,256 bytes.

avrdude: ser_open(): can't open device "\.\COM1": The system cannot find the file specified.
Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.
