I know there are similar threads but more considered
with API or configurations , I'd like to know what is immediate
cause of such messages , what did I wrong that program want fit that ?
This is commonly caused if you have saved a given assembly pointing to a hypothetical toolbox "A" and then you re open the assembly at a later date with toolbox "A" off the network but a new toolbox "B" being pointed to in your system options. Toolbox will build the configuration called for in the assembly if it has not already been done in toolbox "B".
Let me know if this makes sense and if you need any more help.
Probably your diagnose solves that ,
I'm not sure but it has sense as far as I checked that,
