When we try to upload repetier.ino there are verification errors citing content mismatch as the reason for the error and when we try to load Eeprom to clear the code, it doesn't seem to work. We have also had problems with the configuration code. Please advise!

Please leave us another message indicating what version of Arduino that you downloaded. Sometimes you need to use an older version.
Where did you get the firmware you are trying to load, etc.

Please get the firmware located at https://github.com/seemecnc/Repetier-091-ROSTOCKMAX.
The versions of Arduino is located at https://www.arduino.cc/en/Main/Software and you may have to download an older version to get it to compile properly.
Also do not forget to load the Windows driver located at http://download.seemecnc.com/RAMBOUSBDRIVER.zip before installing arduino.

We were able to get the code to upload, but now when we turn the printer on the arms automatically move down and will not stop causing us to have to shut the printer off. we were only able to upload the code by unplugging the motors because the arms are constantly moving and we are worried about them crashing into the heat bed. Please advise.

Without pressing home?

That is odd. The stepper motors need specific sequence of pulses to move.
