I can't add nodes or interfaces, or edit nodes, in my Network Perf Mon program. Haven't tried for months, so not sure when this occured. Running 9.2.47
Run-time error '-2147024893 (80070003)':
Could not load file or assembly 'System Data, Version=126.96.36.199, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the path specified.
Tried renaming SWNetPerfMon.cfg to force a new database, and same error there, so I guess this is not a corrupt database issue.
Mdwyer - I would try reloading or repairing .NET 2.0. That should take care of it.
