Product Activation Error E40-0

Development Getting Started & Setup

Hello;

I have been using Unreal Engine for a while on Windows with no issues, today I tried to download the content examples pack (after an upgrade to 4.7.3) and it keeps failing.

I have restarted the engine and PC but always get the Product Activation Error E40-0.

How can I fix this?

Thanks;

Andy

I have the same problem with UE4 4.7.2 on the launcher.

launcher version 2.0.1.2467307

Mine is now working - Nothing changed on my system so maybe Unreal just catching up after the engine update their end?

It works for me here as well. Thanks.
