Pro Micro: avrdude: ser_send(): write error: sorry no info

I can't get the board to program.

I am running Windows XP, I have loaded the driver and it sees the board, I have loaded promicro-arduino.zip and installed the files.
I have the arduino directory in my programfiles directory and have changed the properties to reflect the new location.

I can select the Pro Micro (I am using the 5V board) and the correct com port, but nothing I do gets me anything except the "write error" message.
I do see the orange LED blink twice when it tries to program but that's all.

I tried "lenoardo" fix and have selected every programmer on the list.

Nothing works.

What am I doing wrong?

I also receive this error but on Win 7 64x with arduino 1.01. I've tried everything! Following the "getting started" guide for the micro went smooth, everything seemed normal until I was asked to upload the modified Blink example, then it simply timed out and never finished uploading - Then this error pops up.

What could cause this?

I'm not sure if your problem is directly related to the first post. I'm having this same problem with Arduino 1.0.1 and some older Pro Micro. I'm guessing the older Pro Micro's with the older bootloaders (before June 19 2012) aren't compatible with the new Pro Micro Addon zip (that gets extracted to the Arduino/hardware folder). For now I can still upload sketches to my Pro Micro's using Arduino 1.0. Hopefully a fix for 1.0.1 comes out soon.

When trying to upload using 1.0.1 (having extracted the Addon zip, restarted Arduino IDE and selecting the Sparkfun Pro Micro 5V/16MHz) I get these errors after the Rx and Tx LED's flash for a while...
