Ignore that comment... it was bad information given to you and doesn't make any sense in your situation.
The activation email with etp.dat attachment is automatically processed by BES when your activation starts.
Since your activation has already started successfully... the message would have been deleted from your inbox already.
If you're still having issues at this point, go through this KB and all related KB articles linked within: Identifying and troubleshooting enterprise activation issues
