Solved!: Sketches not uploading in Win7 RC1

Hello all, i am new to these forums.
I own an arduino duemilanove, which i picked up today after a multi-month break. I just installed the new Win7 RC1, and installed the software, connected the arduino, and attempted to upload a sketch.

My first thought was drivers. Win7 automatically used FTDI driver 2.2.4.0, versus the one packaged with the IDE. I tried installing the included drivers, but it did not help.

I searched the forums, and came up with this. http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1234338562 . I do not have access to any sort of programmer, which seems to be an issue. I have an old pc that has a parallel port, but i do not even know if the old box boots any more.

Anyway, symptoms:
In IDE, running the serial monitor returns "read input switch:1", which does mean it's communicating, right? Also, the tx LED is blinking in the same way it doe when i try and upload a sketch. Copying the default Blink code to the IDE [my work has never progressed much beyond that before, either], and trying to upload displays the "Uploading to IO board..." message. The TX flashes a few times quickly (3?), the L Led flashes twice, the RX Led flashes 3 times slowly and dimly, and then the TX starts flashing quicky. If the IDE loses focus, returning focus to the windows results in the formerly-covered area turning gray. I am then forced to hit the reset button, the IDE comes back to life, and gives me error message
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x00
And tells me to come here!

Any help would be greatly appreciated. I have plans for this little device, if it can get going. Thanks to all!

Did you have it working on XP?

Solved! It was a basic [read: humiliating :-/ ] error on my part. Inside the IDE, the Duemilnove 328 was selected instead of the 168. May this serve as a source of assistance to any poor newb that encounters the same problem. Thank you for your time.
