"Error occured while entering an unnamed file" some message like that i get after couple of seconds when i had hosted the game ??? Whats wrong ? I got the patch etc but still it occurs

Current.thm is having some fun.
Did you try deleting it ?

from all the threads around here that relate to that file it seems that that file is a temp file which consists of the map that is being transfered to you when you play a game... possible data loss from your connection with the host renders the file corrupt and as such the game boots you from that host or whatever... and since a map isnt being transferred anymore the file gets removed.

is this right?

Hmmm... I've seen lots of cases of this error in Worms 2, but never in WWP.
