Object reference not set to an instance of an object

Hi Bill

How can we found what is the source of this error ?
Probably i have some device that is nonexisting, but how can I find which one is it?
Thanks

I’d have to go online & debug the error. Send me detailed instructions on how replicate the issue & I’ll take a look. If I can’t recreate the issue, it’ll be hard for me to determine what’s causing this.

Yeah, that was i afraid of…i can’t tell anything close, 'cause its happening on the startup only.
