Hi, My app doesn't run locally anymore. I have had the problem of a locked svn issue which I solved with TortoiseSVN. I cleaned the deployment directory and clean/unlocked/committed with TortoiseSVN. After this I received the stacktrace below when I try to run my app locally Does anyone have any suggestions? com.mendix.m2ee.api.AdminException: Starting Mendix Runtime failed. at
