Uploading Problem.

Hi guys I am having problems uploading a sketch onto my Arduino, it gives me this error message.

Arduino: 1.6.1 (Windows 8.1), Board: "Arduino Uno"

The sketch name had to be modified. Sketch names can only consist of ASCII characters and numbers (but cannot start with a number). They should also be less than 64 characters long.

Sketch uses 4,724 bytes (14%) of program storage space. Maximum is 32,256 bytes.

Global variables use 145 bytes (7%) of dynamic memory, leaving 1,903 bytes for local variables. Maximum is 2,048 bytes.

This report would have more information with "Show verbose output during compilation" enabled in File > Preferences.

Please help.

You are not communicating with the Uno. The most common reason is that you are communicating with a com port that isn't the Uno.

So lets start from the beginning.

With the board unplugged see what is available under tools->port in the IDE.

Then have a look with the board plugged in. If you get a new port, select that then upload.

If you do not get a new port, then you have a driver issue. Post a link to where you board came from so that we can identify the USB to serial chip and then we can advise further.
