I installed OpenSTA and tried running the script modeler. It crashes when I stop the script collection. The message I get is:

The instruction at "0x73dd11c7" referenced memory at "0x00000004". The memory could not be "read".

I turned the console on and I noticed that when it crashes, I get the following line:
!! selectParseCommand: command is unknow.,<D:\opensta\sf-rw-cvs\ostaw32\src\http\httpgateway\gwhttp\selectcmd. cpp/314>

Any help in troubleshooting this error would be great!
