Hi Wahid, I have just started using Sinergia myself and came accross
this probem too. I worked around it in the following way though the
method may not suit everyone.
I am using VWD 2008 Express, if your using 2005 editions ensure you
install Visual Studio 2005 extensions for .NET Framework 3.0 (Windows
Workflow Foundation)

As i was running 2008 VWD i didnt need to install WWF. I believed that
there was just something wrong with the installation or workflow
database so i took the following action:
1. Renamed the Sinergia folder in wwwroot for backup
2. Backed up Sinergia and sinergia_aspnetdb databases by stopping SQL
Server 2005 Express and copying their mdf/ldf files from C:\Program
Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data
3. Ran setup.bat from C:\Program Files\GLR\Sinergia as I am happy
using all defaults for the install.
4. Chose repair sinergia when asked toward the end of the
installation.
5. Once done replace the files in wwwroot/sinergia/web with my backed
up ones etc to restore. (i did this selecively to ensure only the
files I know have amended since fresh install were overwritten in case
the issue was caused by some sausage finger style typo when looking in
other files)
6. Stopped SQL Server and overwrote the Sinergia and Sinergia_aspnetdb
Databases to restore my data and users/roles etc.
logged into sinergia and everything was running smoothly.
