I just bought the eternal collection. I receive this error while trying to launch D3 from the blizzard client. I have tried a complete wipe and reinstall. I have also tried running as administrator. Here is the most recent Report ID:

This is the Overwatch forum. You can find the Diablo tech support forum here:
Make sure to include your DxDiag there. That error code is only used for the ticket system (you can open a ticket, too, if you want).
