I copypasted this from ubi.com forums; Step 1 Go here: http://www.ubi.com/uk/" onclick="window.open(this.href);return false; Step 2 Click on "Shopping" in top right Step 3 Enter in your login details as per UBI forums. PE-2 Add on should be the first "News" item. If not...
Pe2 is an ad-on for il2+fb+aep+pf.. So if you´ve got it, your game version is 4.05.. I guess we fly mostly with 4.05, (so does most of the il2 community)so you should have it too..
You can download pe-2 from ubi.com, if you have a credit card (i guess?)
