After updating to newest version, I cannot see files and folders on my FTP server. Previous version was OK, I used it to put them there. I can log in successfully (apparently), but the same thing then always happens:

When I say "open this folder" it first fails to do so, then repeats after 10 seconds. The repeat appears to open the folder successfully, but shows it to contain 0 files. Every folder, even root, appears empty; i.e. it fails to see in root the folder it apparently just opened!

I can't tell you much more than that, I am not an FTP expert just a user. It used to work; it no longer works. Help!!!!!
