A very common issue that prevents users from accessing Memsource is that browsers usually have pop-ups disabled by default for every site.
If you are trying to access Memsource but nothing happens, please check if there is an icon on your address bar indicating that pop-ups have been blocked (like the one on the red circle below).
To fix that, click on the icon, choose the option to always allow pop-ups for https://bureau.works and hit "Done" as shown below.
Note: The screenshots above are from Chrome browser. Other browsers also have
similar options to enable/disable pop-up.
