I guess you did not read my previous answer the net of which is: you can't. Sky+ needs two feeds from the LNB (Dish). None odf the other socket will work. The ONLY way you can get Sky+ to work properly is to ask the management company for your flat to provide another feed.
I just thought, before you ask, you cannot split the existing feed in to two. They have to be individual wires from the LNB.
