Quite a bit is going on under the covers to give you the best results possible. There have been some under-the-hood changes which necessitated some breaking changes. As a result all results have been removed to give a clean slate. Don't worry about your lost results: simply reanalyze your TWX files and they will reappear.
Wombat now displays information from new artifacts in IBM BPM 8.5.7 CF 2016.09 release along with the specific version used to create a TWX file.
There are more updates underway so stay tuned!
