2136 patch failing

[NP]

I have just run loki_update on my dedicated server.  It updated to 2126 
ok, but failed part way through updating to 2136 with:

-> PATCH FILE System/Engine.so
xdelta.c:286: /usr/local/games/ut2003_dedicated/System/Engine.so.new:

Sorry if this has already been answered, if so I missed it.

Help ?

Thanks.
