Like I just commented elsewhere (argghh, double post!), this message was only meant to appear once per Trillian install and never show again. It seems some people (like you) have had problems with this in 0.74, but I assume this bug has been fixed in 3.0. If you still get it, make sure your settings files aren't marked read only (often happens if you restore Trillian off a CD backup or similar) otherwise contact Cerulean Studios to let them know this bug is still around.
The "nag screen" was meant to appear once after you used it for a few hundred hours or something, and never reappear (until reinstall). If it kept reappearing for you then either that was a bug in 0.74, or for some reason it couldn't save the "nag screen shown" flag (a read-only settings file is a common reason for this).
I don't know if this screen is still in 3.0 basic, but if it is the same still applies.
