Ashbecker,

I am in the same boat! I am sorry for this inconvenience to you but made me feel better someone was also experiencing error i2501 with no resolution. I feel Square Enix needs to be a little more helpful with this issue and felt I needed to add to your post.

I also contacted support and to no avail I am sure they were reading troubleshooting guides that were in front of them that was absolutely not going to give a resolution to the error for the reasons I was receiving it.

All I was trying to do was purchase a job boost, and received this error without even completing the payment details. I tried a few other things I felt might work before I even contacted them: tried to pay through mobile phone, switched browsers, changed some account info etc. There is nothing wrong with my connection, I am playing from the US and located in the US. All that the Square Enix agent told me I should do is wait a couple days and try again and he would resubmit the ticket to someone who might be able to help me

I did upgrade from a trial account after purchasing Stormblood, and trying to order the job boost on this account. Possibly could have caused some kind of issue...but there should be tons of people who did this.

The job boost and Stormblood was the only reason I came back to the game so its sad that I cannot even take advantage of something that has nothing to do with anything on my side. I guess for now I just level normally. Wanted to unlock RDM sooner than later
