For everyone on this tread trying to look for a solution to this issue I have done a lot of things to resolve this problem. I will list everything I have done as this might be not just one problem. I believe the issued as of today (4/7/14) it has been fixed some how.

1. Your browser maybe blocking a script or Java app.
Some one mentioned this so I removed add blocks and lower the security to allow everything to run (remember to put back to default after you try this). Also updated Java just in case. Also I have tried on another computer and Iphone. This was not my problem but could be yours.

2. The bank of your card is blocking payment because they believe its from a fraud vendor. Just call your bank to see if they noticed the $1 charges on your card and ask if they are blocking payment from that vendor. I got a call from my Chase bank the next day and had to tell them to allow it. (It still did not work for me after I allowed it)

3. If the top options fails then try getting Crysta using paypal ( Id recommend this as you do not see the $1 charges for attempts, paypal just declines the payment if it doe not work which happened to me) Tried today and it worked, it did not work the first 2 times last week.

4. IF all else fails I did have a backup plan which was just to get a time card and because I do not like shady sites I would recommend Amazon.com. Just look up Final Fantasy 14 and in the items there should be a 60 day time card for like $30. (Last time I checked it was there. Never did this option so do not ask me about it if it does not work. I had heard other people call support and force the code in to work but that's about it. The card did say PS3 but from the comments it looks like it works for PC also and that the time also add on to your Vet rewards. Hope this helps anyone.
