Running Hog3 and Hog4 issue

Hey,

i used to swap between Hog3PC and Hog4PC. After every change the connectivity is broken and does not work anymore, e.g. i run Hog3PC , close the App. and run Hog4PC i have to reinstall the Hog4 connectivity and viceversa.
Both Apps are in the Folder "Flying Pig Systems" . Moving the Apps in different Folders does not work at all.....

Any help would be great
Thanks
Marc
