Trying to help my friend who has Hoster but doesn't do forums

He has hoster installed on his external hard drive instead of his desktop. It has worked fine through many imports but now it tells him the save to folder doesn't exist. We have rebuilt the database but that doesn't help. It will import to the "c" drive as I tried that. What I see is that the save to folder shows G:\Songs\. There should be no \ at the end of the songs directory but I cannot get it out. I tried adding a folder but it keeps on with the \. Any ideas?
