It was actually both Dual Sheath Redux and Automatic Variants, the SkyProck Unified Manager didn't seem to patch them right and corrupted them so I reinstalled both and didn't use the SUM. Still having a small problem getting Dual Sheath to work though, the normal patcher that comes with it is patching but the patch isn't being detected even though it's activated and in the load order near the end.
Finally finished getting everything together and now I can't get Skyrim to start. I start SKSE or Skyrim through MO and Uncapper will pop up then about a minute later Skyrim pops up (with borders even though borderless window is installed) and I get a CTD soon after the Skyrim emblem shows up. How should I try to diagnose this, and what should I look for?
