I got this error, I fixed it on my end, buy FYI -
The data files could not be loaded due to errors. Hero Lab will now attempt to load them in recovery mode. Once loaded, you can access the editor as normal to correct any errors.
The following errors occurred:
File: PFRPG_Psionics_Unleashed.user (line 17017) - Thing - Duplicate record encountered ('raVulnSun')
File: PFRPG_Psionics_Unleashed.user (line 17213) - Thing - Duplicate record encountered ('rCrysmal')
