recently i bought all of the Fallout NV addons on steam and started a new game, with all addons active from the beginning.
The "Main"-game works completly without crashed or freezes, but when i try to move to an addon-area (like zion or the are of old world blues) the game just crashes. They game crashes usually about 1-2 sec after starting to load the new area.
I already tryed verifying my data on Steam and it always told me that "installscript.vdf" cannot be verified. I tried to deleteand re-download it, but it didn't help.
After searching for some days, i have completly no clue, whats wrong with that addons.
I hope somebody know the reason for that problem.
Thank you for help
