Based on Members' feedback, we have now sent a new set of simplified instructions via E-Mail.
If you still haven't received it, please check your Spam/Junk folders.
Thank you for your patience during this transition process.
Thanks KVS. I got it to work and have it up and running with the GTC credentials. I appreciate your help but still contend that the instructions are most bizarre. The oddest part was the decoder for the 'site code' part that precedes the username in the KVS settings.
It seems to take a lot longer to return flight availability than the old methods but at least it's now working again.
If anyone needs any help from an independent source who has gone through the process feel free to send me a PM.
