I have the same problem.
The output in the ScadaServerSvc is:
2015-03-21 12:36:04 <I5-4570><SYSTEM><ACT> ScadaServerService is started
2015-03-21 12:36:04 <I5-4570><SYSTEM><ERR> The configuration database in DAT format directory does not exist.
The interface directory does not exist.
The archive in DAT format directory does not exist.
The archive copy in DAT format directory does not exist.
2015-03-21 12:36:04 <I5-4570><SYSTEM><ERR> Normal program execution is impossible.
Thanks in advance.
