I had this problem starting yesterday, when I first downloaded the updated "Aslains_WoT_Modpack_Installer_v.1.4.0.0_06", and have downladed it again today after uninstalling the modpack and reinstalling it after a re-start.
When I start the game, it runs as expected, until it gets to the garage, which is slightly grayed-out and has the 'Aslain' logo spinning.
It NEVER goes further, even after a couple of computer re-starts and game restarts.
Yes, once I uninstall the modpack, I can run the game as usual.
HELP ME, PLEASE!
I NEED those amazing life-like sounds and all the other mods I choose! LOL
