So im in a bit of a pickle i had originally set my mods to download to a hard drive that has failed on me. Now when i try to change the download directory for mods to a different drive it says it cant beacause it cant find the old directory. how do i get this fixed or at lest temporally switch back to NMM which still has all my mods

so my skyrim keeps crashing after alot of googiling i enabled papyrus logs and at the bottom of the log it gives me this 1/2015 - 06:20:07PM] Error: Cannot call ForceRefTo() on a None object, aborting function call stack: [None].USKPCWCampLeadersFixScript.OnUpdate() - "USKPCWCampLeadersFixScript.psc" Line 43 [01/11/2015 - 06:20:07PM] Error: Cannot call ForceRefTo() on a None object, aborting function call stack: [None].USKPCWCampLeadersFixScript.OnUpdate() - "USKPCWCampLeadersFixScript.psc" Line 44 [01/11/2015 - 06:20:07PM] Error: Unable to call UnregisterForUpdate - no native object bound to the script object, or object is of incorrect type stack: [None].USKPCWCampLeadersFixScript.UnregisterForUpdate() - "<native>" Line ?
