Thank you for your replies Simsample and Riggs.
I did'nt bother installing WA nor HELS for now, I want to solve this first.
I don't have any .dbc files in my mods folder yet, for the same reason.
My game used to be installed in the default path (C:\Program Files (x86)\Electronic Arts\). I tried changing the location because I had to test different things to figure out how to solve the problem and wanted to see if it could be du to UAC (in Program Files authorization is needed to add/remove/moddify anything but is not in other locations). Now the game is back in the default place because it didn't change anything anyway.
I also considered the possibility of a new update of my firewall/antivirus software being responsible of this mess but I installed the same software on my husband's computer (I deal with kids and husband computers at home, soft and hardware because I like it
) and he has the sames updates as I do so why should it work on his and not on mine ?
I tried a lot of different resouce.cfg, including this one which doesn't work either (my game is in french, so "The Sims" is "Les Sims") :
Priority 500
PackedFile Mods/DCCache/*.dbc
PackedFile Mods/Packages/*.package
PackedFile Mods/Packages/*/*.package
PackedFile Mods/Packages/*/*/*.package
PackedFile Mods/Packages/*/*/*/*.package
PackedFile Mods/Packages/*/*/*/*/*.package
PackedFile ../../../Users/Topaze/DOCUME~1/ELECTR~1/LESSIM~1/DCCache/*.dbc
PackedFile ../../../Users/Topaze/DOCUME~1/ELECTR~1/LESSIM~1/Mods/*.package
It looks like, for some obscure reason (to me) the resource.cfg file isn't read. I don't understand why it did before and stopped all of a sudden. I could try uninstalling a game I tried recently (but can't even remember if it was before or after framework stopped working) but I would really be surprised if it had anything to with it.
Delphy's Dashboard tool doesn't either find any file located in the mods directory as it used to.
