Orchid Load Family

Orchid version 130.0.7, Dynamo 1.3.2.2480 and I am trying to update a project with different annotation families using the File_LoadFamily node.Sometimes the families load and sometimes they don’t, and the output is always null. So I opened the node and pasted it in to try and figure out what is wrong and I get this error.

Traceback (most recent call last):
File ",line 43 in
Exception The document must not be
modifiable before calling LoadFamily. Any
open transaction must be closed prior the call.

Any ideas?!
Error|502x500

Thanks, that did the trick!
