With 1.1.1, on a directory that you get an error, if you change the name to something simple like A, will it start working? There should be no difference in the directory name handling in the 2 versions. My first guess of the error you had would be that the WUP files are incomplete or bad. I recommend to use New-NUS-Grabber to see if the WUP will fully decrypt with all files including Meta directory. If it doesn't then the WUP is incomplete or bad.
