My patches do apply to RME 4.1.1. However, your problem is different. First, your server is localized for French. This is not supported. You must change the locale to US English. Mais, je parle un peu français, and it appears your RME database is bad. You're missing a vital column, isPOECapable, in your PhysicalElement table.
This column was added in RME 4.1.1, so it looks like your upgrade to RME 4.1.1 did not work properly. You can try reinstalling the LMS 3.0.1 upgrade, but there may be a deeper problem preventing the database update script from running.
