ActiveHome Pro SDK Random Error

[Drini]

I have installed ActiveHome Pro & ActiveHome
Pro SDK to control lamps, appliances etc
form Internet (web server pruning at home)
and from phone (I wrote a small perl program
to control & read the voice modem). at
present I am testing those programs with SDK
ahcmd command.
My problem is: Randomly, execution of ahcmd
pops up a windows error dialog box. Any
suggestions?
