0x8000FFFF: Catastrophic failure

[MeAndI]

Hi,

I've create a custom com object and I use it as follow:

set test = Server.CreateObject(myObject.classID)
' --> all OK the istance of the object is correctly created

retval = test.function1(par1, par2 ...)
' --> as soon as I call every function of my com object the system returns
the following error: 0x8000FFFF: catastrophic failure.
I do not know why

please help
Thank, bye

What language is the com object built in?
What does the function do?
What does the declaration for the function look like?
