Hi Sailor,
I can't answer your question directly but have you had a look at the following webpages which contain information relevant to the issue:
http://support.tixati.com/ip%20filter%20view
http://support.tixati.com/add%20ip%20filter
The "add IP filter" webpage, under the heading "IP List Source", says that:
Tixati accepts lists in the "Description:ip-range" (Bluetack/PG) format, and the "ip-range,#,description" (eMule) format.
(Personally, on that webpage, I think Tixati could improve things a bit by showing a couple of short
examples of an actual list in both formats to show users how to correctly make the blocklist themselves. Come on Tixati - help your users out!)
Maybe you can get it to work from information in those pages. If you do remember to post the solution to your query up here so that you help other users.
