Hello all
I know i am new here but i am hoping that someone on here might be able to help

Last night i was using my flash wirelessly having my Nikon D90 pop up flash as the master and the SB-600 as the slave now it took about 40 shots working no problem and then the pop up flash stopped firing and so i put all the batteries on charge to make sure that wasnt the issue but now i cannot get the SB-600 to fire after the pop up flash no settings have been changed and if i put the SB-600 on the camera on TTL then it works no problem

please has any one got any suggestions

Many thanks in advance

Karl
