I find when this happens it's best to delete your folder from the custom folders, this forces toribash to re download your stuff fresh, and normally fixes this.
instructions:
1: go to C
Games\Tribash x.xx\custom\
(Assuming you installed toribash in the default location)
(where x.xx = version number)
2: find the folder with your name
3: delete it
4: load up toribash and download your stuff again.
