I was having the same problem which is how I found this forum.
I discovered that there was one file I was trying to recover that had a VERY log file name that was causing the "Maximum path length exceeded" problem.
Go through your files and make sure that any files that have unusually long file names are unchecked. Everything should recover fine after that.
