Regarding Error Message after installing PLOTSTAMP

I sent this message two days ago, and it is gone from my newsreader. Does anybody know if there was a reply, and what that reply was?
Message follows:
Exception in C:\Program Files\ACAD 2000\acpltstamp.arx ARX Command Unhandled Exception C1111115 (Access Violation Reading 0x8c34) at address 90DFB5H
Can anybody translate this for me?
