Please help me with problem on SE V PBW

[Dogboy]

I've created a new game for friends. Two players have so far signed up. We are playing SE V v 1.71 with the 1.14a Balance Mod.

I have three questions:

1) Once they upload their races, do I manually set up the game and upload a file? I imagine I must, else how could I set up all the game parameters. However, this was not clear from the FAQ.

2) For both of the players who have uploaded so far, when I choose "accept player" I get the error message below. One question: when players indicate empire name upon signing up, is that the file name they used when saving their race, or the name they selected in the game? Here is the error. Any advice would be appreciated!

3) As host, can I just sign up as I would if I were a normal player?) Thanks!
