Linked WoWs and battle net accounts

so,

Have 4 linked wow's and 1 main - been working just fine.

Now, I merged all 5 accounts to 1 battle net account.

When I run the "real" wow directory, I can log in fine - but all of the linked a very wierd error - almost like a network error - "there was an error loging in...", if I instead input the old name, it works fine until it tells me that the account needs to log in via b-net account....

Any ideas? could my fwall be stopping access to bnet servers from clones or something?

Hiya, do you have the battle.net.dll in the copied folders? maybe worth just updating your exe/dlls/etc *shrugs*

Many thanks, that fixed it :D
