On a monthly basis I have been backing up qkn to another computer on the network (aside from b/u whenever I exit qkn to another hard drive on this computer). Today is the first time I've tried since installing qp06; the drive is mapped but I am getting message that drive can't be accessed. Qkn is the only thing that has changed since last successful backup & am no longer using za on either computer; all other files can be opened & edited from both computers & printer/file sharing are checked for both. Any ideas?
