Hello, and thank you for using this service.

Sorry to hear you are having trouble. I will help you now.

Would you like for me to make a remote connection to your computer to fix the problem with Thunderbird? NOTE: There is an additional fee for remote services, but it's faster, easier , and more effective at solving problems like this.

I take it by "making a remote" you mean you'll take over my computer and operate it by remote control. You don't tell me what your "additional fee" is. My problem is so simple that anyone who knows even a little about Thunderbird should be able to tell me in text words how I can solve my problem. Do you know even a little about Thunderbird?
