RW won't upload for no apparent reason

[teefers (Doug Bennett)]

It seems like you’ve got two posts going for the same issue?

Just refuses to upload for no obvious reason

Here’s a surprise: RW decided not to upload. The server is fine, I upload files easily through Cyberduck. I haven’t changed a thing since last using RW a month ago. It just says now: COULDN’T SIGN INTO YOUR FTP SERVER. Any help? Please!
