Error message--Buffered memory access not supported

I've tried all the solutions I could find on the forum, but none of them worked for the two robots I bought for my students. I get the following error message when trying to upload to the Arduino Robot:

Found programmer: Id = "B§$ "; type = Software Version = . ; Hardware Version = .
avrdude: error: buffered memory access not supported. Maybe it isn't a butterfly/AVR109 but a AVR910 device?

The solutions I've tried are:
- Tapping the reset button twice and then clicking upload.
- Holding down the reset button while compiling is occurring and then releasing it when uploading starts.
- Tapping the reset button twice when compiling is almost finished.
- Changing the Programmer from "AVRISP mkII" to "USBasp"

We were able to upload programs to robot # 1 for about a week before getting the error message. Students did not use robot # 2. I was able to upload about two programs to robot # 2 before getting the error message. The problem occurs whether I'm using a Windows 8.1 machine or an XP machine.

The IDE version I'm using is 1.0.5-r2.
