Hello Roger!
I've managed to restore my course.
My way is both sad and funny but worked for me.
I installed the newest Debian (Jessie) on a test server, set up Apache, PHP and Mysql, installed newest Moodle 2.8 and restored my course using Moosh.
Since I've got about 120 "problematic” courses from two moodle installation (I want to merge these two Moodle sites) and about 500 "non-problematic” - I figured out that I will restore them in linux environment and then try to convert DB to MSSQL and go back to windows server, IIS and SQL Server 2012.
Good luck in your moodling!
Lucas.
