Start over, what happens?
Unplug the UNO
Close all IDE windows
Plug UNO back in
Start up the IDE
Select UNO
Select the correct COM port

Try a new USB cable
Try a different USB port
Have you every downloaded to the UNO successfully prior?
You may need a new controller or re-burn the bootloader

interesting I am getting the same error trying to learn some HTML...

this error:

avrdude: verification error, first mismatch at byte 0x7800
0x8c != 0xff
avrdude: verification error; content mismatch

the sketch attached:

you can see I am just trying to move the HTML off to the SD card...

compiles to: Binary sketch size: 31,678 bytes (of a 32,256 byte maximum)

I have a similar one (with SD library, but without the call to the file) that works. On my UNO with the stock Wiznet Shield...

I also have the F() macro giving me this:

NTPClockWithWebPageWithSD.ino: In function 'void updateLCD()':
NTPClockWithWebPageWithSD.ino:95: warning: only initialized variables can be placed into program memory area

Yes, I worked down the memory requirements, removed the String class.
