As noted in another thread that isn't getting any input, I have a new zd install (zdesktop_1_0_4_build_1833_win32.exe) on a windows 7 box that has a broken email account. It was added, then during the attempt to copy the three folders over from my other zd install became corrupted. I tried to remove it using the zd interface. It's not listed any more, but if I try to add that email account back in, zd tells me it already exists. How can I fix this?
