BOUML UML Root mode protection error message

I am using a BOUML free UML 2 tool box allowing us to specify code in languages like C++, Java and others.
I have installed it on my Win 2003 server with SP 2. I am receiving an error message regarding the BOUML UML :
DO NOT CONFIRM
Root mode protection
This mode allows me to develop BOUML
do NOT confirm to avoid a disaster!!!
Confirm?
Yes No
I am not sure what the reason for this message to pop up is? If anyone has come across something like this, please help?
