There can be many reasons contributing to this failure. Below are some of the possible problem areas;:-
1. The environment was created in a different software release: Abacus only supports environment created in the current release AND one release before. If the environment was created long time ago, there is a chance that the environment won't be able to be loaded and used.
2. The environment is corrupted: An Abacus environment file is actually a collection of multiple files. If any of these files got corrupted, Abacus will not be able to extract the data to construct a configuration for a test. Users need to re-create the environment from scratch.
3. The Abacus software / firmware is corrupted: Users may need to perform an Emergency Recovery to get the Abacus System back to its original condition. If this does not help, users may even need to re-install the Abacus Software in the PC.
