BPC v10 SP13 fails to copy environment

Hi all.

I need to copy an Environment (AppSet) in v10 SP13.

However, every time I try, it creates the Webfolders, FileDB and database, but when it gets to creating OLAP, it just stops.

It does nothing, then after about an hour, I get a Server Timeout.

The system was fine when creating the EnvironmentShell and I was able to fully restore an Environment from a DEV system, but it just won't let me copy the Environment.

There is nothing in tblLogs and nothing in Eventvwr on either server (App/SQL).

I have also confirmed that the required ports are open (80, 443, 2382, 2383, Custom SQL Port)

Any ideas, anyone?

It's really starting to annoy me now.

Thanks
