Also, with beta patches, EWoM won't fully load unless/until you establish an Internet connection. However, EWoM without any 'beta' patches will load fine with no Internet connection active.
easiest thing is to have Internet off, and load EWoM. If you load from Impulse, currently it will say its 'working in offline mode.' I have no idea what will happen when the 'other' company (gamestop? I think) takes over Impulse... so watch for behavior changes if you want to be sure nothing is going out over the internet to your ladder, or trophy, etc. Hope this helps
