I know this should be an wasy error to find int eh conf file, but line 320 looks fine to me, nd I retyped it to make sure there were no hidden characters. Here is the error avrdude spits out through the IDE:
Binary sketch size: 450 bytes (of a 32256 byte maximum)
error at C:\Users\jim\Desktop\arduino-0022\hardware/tools/avr/etc/avrdude.conf:320 unrecognized character: "a"
Argh! Either the forum alters the file (e.g. changes line-feeds to carriage-return-line-feeds) or the you will need the latest avrdude to go with the new configuration file.
The choices available to you...
● I'll put the file somewhere else and you try again
● You locate the original source file (I think the project is hosted on SourceForge), download it, and try again
● You can "upgrade" to the latest AVR-GCC compiler...http://arduino.cc/forum/index.php/topic,60649.msg437771.html#msg437771
If you would like to try the first choice, just let me know and I'll find a different home for the file.
