The error message is likely due to a conflict between two different versions of Firebird. Our software is compatible with Firebird 1.5.x.x. and Firebird 2.0.x.x. In other words, another application on the computer is using a version of Firebird that conflicts with what Gradience is using.
Assuming this is the case in your situation, there [should not] be any problem as long as you can get your [other] application to use one of versions of Firebird with which Gradience is compatible. Links to both are provided below.
