Unable to get past launcher/updater. FIXED [30605][20448][10009][10019].

I did everything i could to my computer before calling support after which i was told the problem was my ISP. After calling my ISP i found out not only was it not my ISP. It must be the Software of the program (final fantasy 14's launcher/updater). So after exhausting all the support i was given i almost gave up on the game. Tell i thought maybe i accidentally downloaded something interfering with the launcher. So i went into my downloaded and deleted everything i downloaded this month and part of last. Games/setups/torrents ETC. everything dated to the time i thought i might have had the problem. This did not fix the problem. So after that i proceed to my computer files except the ones i know were part of the system. I deleted everything up to the desired date no matter what they might be other games/updates/tool bars ETC. Then a miracle happened it worked. SO no matter what your told in other forums, support, and friends this fixed my problem in a heart beat.

Delete any programs downloaded after/ON a date you know it worked. (((((((((BE WARNED DO NOT DELETE SYSTEM FILES))))))) This will mess up your computer and may be permanent. I'm not liable for you doing this if you don't know what your files are. DO NOT touch them you will need someone who knows what they are doing to do this for you. Have a nice day and see you all in Eorzea!!! :):) :D:D :p:p

Did you try a ipconfig /release and ipconfig /renew?

the game launcher seems to have issues with some IP's but that is a quick fix.
