DavyJonesFootlocker greetings.
I am using a way not to reinstall the game when it is corrupted or altered by some mod.
First of all you must have enough space on your hard drive.
Then you have a copy of the
DATA folder, which as you know is inside
SH5 directory in a different direction from where you are, if you compress it much better that way does not occupy much space on your disk.
Then you did this backup, install the mod you are going to install, if the game is corrupted install, unzip the
DATA file and replace it with the original which is on the board of
SH5.
To me it has worked with most of the mod, when I had the problems ...
I hope you will be helpful
