I've been using this for months now. I'm using the most recent version. No changes on my end other than the game update this morning. Was working fine last night. Now I get an error after clicking "select" a window pops up that says:
"Hook64 could not find some data in the process.
This could be due to a non-compatible version of the game or
a game udpate.
Please check gamemodi.net for updates or contact Sorien.
Hook64 Version 1.6.6.0, Error #: ESO_10"
