Eu4 Not Launching For Mac

Eu4 not launch for macEu4 Not Launching For Mac

Hello, I have a Mac computer with Mac OS X 10.7.5, And EUIV installed through Steam. Everything was working fine but since yesterday I cannot launch the game anymore, it tells me that 'EuropaUniversalisIV quit unexpectedly'. I can then click on Report (I have coped-pasted what it says below), or Reopen. When I click on Reopen, a pre-launch window (never seen before) opens, I click then on start 'EUIV' but the game starts without any of the DLCs (I have all of them including CoP and they all show as inactive even though they were all selected in this new pre-launch screen). Also, it would not allow me to select the iron man mode. Apologies in advance about my ignorance - this is the first time I post on this forum. I have tried to do it in the Technical support section, but the Games Menu does not offer me the possibility to register my game.
