Ahh sorry, misunderstood the question...., try this instead:
Find the file: valid_takeovers_only.edt (it is located in your game filing system, under Football Manager 2016, and then under DB, and 1601, edt).
There you can change which legal takeovers there is for a nation (and therefor your club) Simply remove all the isues from Greece, that will mean, that it is more likely, that there are someone who will take over the club..., but you will have to start a new game, to make it run...
And if you anyway has to start a new game, just do as Prinox says, and change the outcome of the clubs struckture in the Editor..., but change the edt-file as well, is always nice to get some more options, if the club has to comped at the highest status. But you can't change it in the game you are playing using FMRTE... sorry.
