Lightroom 5 - Building Web Gallery hangs and then fails (worked versions 3, 4 no problems)

Question

The key and only reason I own and use Lightroom is to create and manage my 50,000+ family photos spanning through 3 centuries.  (1800s, 1900s, 2000s)   
www.L-Y-N-C-H.com
With Lightroom 5 the web galleries I have previously created and uploaded and as well the customer user presets I have created OR the standard templates are now ALL hanging and failing during the "Upload Web Photo Gallary after exporting all the images, etc. 
The app does report the folders and files exist on the server so it must be logging in succesfully and parsing files and directories etc? 
It then goes off and is looping around "Building Web Photo Gallery" and after about 5 plus minutes it fails with a " an error occured sending the file:  connection to the server failed" 
Which is probably just because it is broken and then times out because of failure.
I have checked, triple checked, changed passwords and also later uploaded FTP files and etc and actually am now having to EXPORT the whole gallery locally via LR5 and then FTP by hand the whole thing to the website.
defeats the whole reason i have been buying this product?
EVERYTHING works great except Lightroom 5 is now broken for this task to me.  All I did was send money to upgrade and install product and upgrade libraries.......so i can't go back right?

March 2014: After 31 years of emailing and internet use, our/my entire email system has recently been bombarded by huge volumes of spam, hackers, and robo-mailer daemons so I am taking drastic actions to reduce the 1,000s of unwanted emails we/I get everyday. HostGator (my ISP for email and L-Y-N-C-H.com) SpamBlocker and now BoxTrapper are fully implemented. 
This process follows 2 paths: 
1) Wait and allow me additional time on your first use for me to see your email and then add your ISP/URL and email to my accepted senders list.  (whitelist)
2) Reply to the link below to verify you are not a robomailer or spambot, etc.
