It is possible one or more of these files are corrupted. To determine which one, you will need to rename the following file FTSessionControl to FTSessionControl_old, which sets (Security Path, Global Defaults Path, and Activity Log Path) back to default. You can find this file here:
C:\ProgramData\Foxtrot Suite or at the shared location “ UNC Path”
Once Foxtrot Admin is opened you can set your license path back to the correct path. To see which file is corrupt you will then need to set the paths for Security Path, Global Defaults Path and Activity Log Path back to the same as the license path. Only set one at a time and save Foxtrot Admin. After you change one path close Foxtrot Admin and try getting back into it. If you can you know that file is not corrupt.
In your license path you will find the following files:
Security Path: FTConfiguration.mdb
Global Defaults Path: FTGlobals.mdb
Activity Log Path: FTSystem.mdb
Once you find out the path that stops you from accessing Foxtrot admin you will then know the corrupt file. You can rename/replace the corrupt file from a backup or if you do not have a backup file you can rename the file like you did earlier to the FTSessionControl file and Foxtrot will recreate the file.
