DI - Connection and Standard add-ons

Hi,

I have same problem running my add-on togheter with the standard add-ons : at the first run of SBO i get a variable error (Failed connecting to company DB, Error ... Method ... , Initialization failed), at the further runs all it's ok.

I have installed :

Outlook integration

DTW

Support client

Payment engine

and My add-on with UI and DI

Have you an idea of this strange behaviour ?
