hum, please, this is not a forum for requests about external softwares.

if you want to pay the flashchat, just go to theirsite and contact them directly:
http://www.tufat.com/

vBulletin is not a single way related to tufat.com, so we/coders and them/Jelsoft can't help in any way possible.

and if you read well on their site, you have to pay the 5$ fee to have access to the files/support... there is no trick, many admins here already have paid for the script and are using it ... but we can't help more, sorry.
