not sure here, but methinks that all of the previous readers have totally missed it...

you say "...downloaded the free trial ver. of LW...."

what I'm reading here is that you downloaded the basic (free, but not a trial version as there is NO expiration timer) version of LW...when you started using it you started having outlook (express?) start giving some sort of 'pop-up'....do you mean that when you open LW, outlook also opens up?

not sure what the solution here is, as I see no obvioius option in outlook express that would cause or solve this problem...I've never had any occurence remotely similar to this with either outlook express or office outlook (noticed a few other problems over time, but not that one) and I've had LW installed on my machine many times, and of course since outlook express is part of the basic windoze OS install, I, like you, installed LW after outlook express...

the only thing that seems 'obvious' to me is that you may have some sort of corruption in your registry (possible caused by some other program) that is causing this conflict....if you get lucky you might actually get in contact with a person at M$ who not only speaks english worth a flip, but might also actually have the knowledge to work you through your registry to help you troubleshoot...
