I never had a selector crash. Did you install the pack on 4.12 game version?
If you got the correct game version, post your logfile:

Also make sure that you got the correct screen resolution set in the conf.ini, the install guide has a sample for 1080p nvidia card:

Just done a fresh install of base game then 4.12.2 and finally vp mod no luck... followed guide carefully!
resolution is correct, even tried copying in the sample.
The only log I can get is this:
