Command line error in 8.50.25.47 but not in GUI

Hi, have a ‘mystery’ problem with the command line.
If I run the following from a command prompt:
C:\Documents and Settings\adrianda>"C:\Program Files\Red Gate\SQL Data Compare 8\SQLDataCompare"/project:"D:\NDW\test1.sdc"
It writes the following to the console:
Registering databases
Mapping
Comparing databases
Error: Object reference not set to an instance of an object.
If I run the same project in the GUI environment it functions correctly.
The following outlines steps I’ve take to try and isolate (unsuccessfully) the problem:
• The above project has been re-created from scratch and only looks to compare a single object in an attempt to narrow down the problem
• I’ve copied the same project to another machine with RedGate installed, where it will run correctly in the GUI AND command line
• I’ve done various other tests to eliminate permission and related problems
My current thoughts are it must be an environment difference. What do I need to do to resolve the issue?

Have you tried reinstalling SQL Data Compare? If it works on another machine, then as you suspect, it must be environmental.
I would also suggest trying the patch version available here
Any other ideas?
Do you get the same problem if you use the command line switches rather than calling a project file? e.g.
C:\Documents and Settings\adrianda>"C:\Program Files\Red Gate\SQL Data Compare 8\SQLDataCompare"/db1:SourceDb /db2:Targetdb
C:\Program Files\Red Gate\SQL Data Compare 8>sqldatacompare /db1:SouthComm_Syste
m /db2:NDW_Reporting /v
