Hello Aslain,
thank you for the prompt reply and for the help
Since I had uninstalled all mods ("reset" option on the installer), I re-installed all of them after following your instructions.
Unsurprisingly, the res_mod folder was changed and the game hung up on start up like yesterday, so I had to replace res_mods again.
It seems to be working, so far
I'll let you know if the mods are operational
