This is exactly right. I just forgot to change the version number in the program.I can answer the first question...1.61 and 1.62 are identical, but a file was missing in 1.61. So the file was added and renumbered 1.62, I guess so people know its not the version with the missing file.
As far as the second problem, I know why it gives the error. It's because the listview (the list that has the Players' name on them) requires "keys" to associate different items in the list. The Key is just the player ID. I hadn't thought about it until now, but technically, someone could change the IDs and accidentally duplicate them. Also, if you export a player (or players), then import them without removing the identical players, this could happen too. Chances are it was one of these two things that messed it up.
The import/export functions are still in there "beta" stage, so there will be some bugs. I will try to account for this particular one next release.
