Need insight into what this new error means?
===

This is a .NET error:

    Error Message: String was not recognized as a valid Boolean.
    Error Source : mscorlib

This may be a bit cryptic-sounding but that's all I have to show. How to go about retracing what happened... I really need help on this, how can this come up if it didn't appear before, though the application was the same.
 thanks
