Issue with Sage 50 US 2015 Premium on server re-installed on a new laptop.

SOLVED

We use Sage 50 on server since 2015 for 3 users. 

Recently I installed the same software on my New laptop and it doesn't work the same way smooth as on my old laptop.

For several part of the menu, a window open, then close immediately and Sage 50 freeze and closed.

I tried to install It on another separate laptop as standalone, but exactly the same issue occurred.

Indeed our subscription plan is expired, but the system still works well on other PC and laptops.

I really need to find a way to have it working as standalone for my CFO as the Covid-19 closed down was declared

by the Government Yesterday and she has no other options to work with the system.

Is anyone can help?
