I can't log in to FTP

[Robbie Robb]

Hmm....that doesn't sound good. And it MAY be the cause of your problems. I'm pretty freakin' sure that ssleay32.dll is the DLL file that controls the secure socket layer connection between the software and the servers - if it's not registered that would probably explain why you're not able to connect.

When you uninstalled the software previously did you go into the directory and verify that the files were deleted from there? Here's my next suggestion:
Uninstall the FT software once again (yeah, I know, for about the gazillionth time) and go in and make sure everything is deleted out of there.
Reinstall FT into a different directory - maybe add a '2' or something to the end. I'm pretty sure that changing installation location will force Windows to reregister all DLL files for this program.

EDIT (to add): if this DOES work, don't forget to change the install location inside PT and PAHUD (or any other program that looks at the FT directory).
