hi i just accepted a batlle. i foudn it is against bedouin that are in a book i don't have
when i start the battle it returns an error (something like cannot write Mac:hd etc...

i presume the error is because the fight is against an opponent from a book i don't have.
In this case:
a) why it allows me to accept the fight ?
b) why i cannot abort the acceptance (i think i created something that will remain blocked forever ...

Can you be more specific. When you get this message can you highlight the message and select copy. Then paste it to this forum. Also any more information on what you are challenging with what would be great.
