I can't log in to FTP

[Robbie Robb]

Okay, this helps then.

We've now went directly from your computer to your internet connection and cannot connect to FT. This tells me one of two things has happened:
1) Something in your computer's configuration has changed that is forbidding FT from connecting to its servers. This could be a firewall setting (as previously mentioned and checked), or some type of viral program preventing it.
2) You ISP is actively blocking access to the ports required by Full Tilt.

#2 is the least likely of the options but here's the ideal way to confirm it: get a friends computer (ideally a laptop for its portability) that is known to be able to connect to FT from a different location. Bring it over to your place and connect directly to your internet service. If your friend can startup FT then we know it isn't a problem with #2, leaving, sadly #1 as the probable cause. If it turns out #1 is the cause, backup all your important stuff and reformat and reinstall everything. For the record, when doing a reinstall, I recommend splitting your hard drive into at least two partitions with the C: drive holding nothing but Windows and MS Office (as well as your various drivers). Move all other programs onto the other partition(s). I even move My Documents off the C: drive onto a different partition. The advantage to this method is if you ever need to reformat and reinstall you're not losing any data as you're only reformatting the C: partition. While you may still need to reinstall your other programs you'll probably fine that some will run just fine without actually being reinstalled.

So, what happens if friend's computer, known to connect to FT from a different location will not connect to FT at your place? Well, the next step (and actually I would recommend this step regardless) is to try YOUR computer at a different location. If you connect from a different location - time to call your ISP and start raising holy hell.

Prior to doing that, I would recommend emailing FT support once again and let them know your findings and what you suspect. Ask them exactly what ports and/or range of ports the ISP needs to have available for FT to do its thing. Perhaps FT will step in and contact your ISP as its in their interest to make sure they are not being blocked. (well okay, we're not talking about Stars support here so it's unlikely, but let's dream for a minute)
