Good day to you all. I'm using Mod Organizer with Skyrim, and have for many months without issue. However, within the last week I have started to get failures with FNIS where it claims that it cannot find a file that does exist on my harddrive. I have a sneaking suspicion that the latest round of Microsoft Windows patches is to blame, as I got this error after updating, but I have no proof as yet. I'm running Windows 8.1-x64. The exact error is ERROR(53): "Could not find file 'D:\Program Files (x86)\Steam\steamapps\common\Skyrim\data\meshes\actors\dlc02\benthiclurker\behaviors\benthiclurkerbehavior.hkx'.", which is in the 'Fores New Idles in Skyrim - FNIS' mod. I did verify that the file is not corrupted (redownloaded FNIS, ran chkdsk, and made sure I could open it with Notepad++), and I installed FreeCommander XE and verified that the file is in the virtual tree structure properly. I ran into this problem using ModOrganizer version 1.2.18, and updated to 1.3.1b to see if that might fix the problem, but had no luck. In addition, I found the following in the ModOrganizer log: Following up on that I tried to delete the file in overwrite\...\temporary_logs, and FNIS did recreate it, then halt with the same error. Any ideas on what I can try next, or is there any more information I can provide to help diagnose this issue? Thank you.
