Not allowing my program access

Instead of using aim and msn messengers i use a program called Trillian. A
feature that trillian has is keeping log files of conversations i have
between friends, this feature is used all the time for me. But with UAC
turned on, trillian doesnt have access to create / edit the log file on my
hard drive. UAC never prompted me if i want to 'allow' access for it to do
this or anything, it just denied it. I turned off the UAC feature and now it
works fine. My problem is, that i want the UAC feature on, but i want it to
give access to my program, is there any way inwhich i can do this?


Thanks,
Michael
