Darkoath13 Posted March 19, 2016 Share Posted March 19, 2016 My game will not launch and i get this error message: Unable to find masterfile: AOS.esp Required by: ISCompendium AOS Patch.esp I do not have a mod that is called ISCompendium or AOS. Is this part of another mod? Not sure which mod to delete or what to load to fix this? Searching mods on nexus didnot turn up anything. Any suggestions. Sorry I am new to using mods...

Are you sure you do not have either of the above two mods?If you don't, I really have no clue how the patch .esp found its way into you data folder.
