That is a long time known MePo configuration crash problem. I reported it ~year ago with easy way how to reproduce it.
This is caused by error in registry when filter is not installed/uninstalled correctly.
If you have SAF installed, please send me your SAF logs.
To identify source of the problem - START - SAT - Tools - Filmerit.
Here click on "bug" icon - this will show only bugs. expand it fully and post screenshot here. I will then identify the source of the problem. And possibly add a registry fix in my SAF if such bug is detected.
