BACNET Client NOT working on current LM Version

[domotiqa]

Hi,
I tried to install the bacnet package ipk above on LM 2.6.2 (with install from file, I checked the checkbox of signature - allow to install package without signature).
I have a message "action failed, please try again later)

but I can see the module installed in the list but I don't have the tab on configurator and can't use bacnet library in script.
Do you have idea ?
