[Plugin: The Events Calendar] Formatting Problems – Using Thesis Thesis Skin

First things first…I am not a designer. My knowledge of CSS is essentially limited to what I can copy and paste.

I am creating a local event based site using Thesis along with a premium Thesis skin. The skin is ThesisPlay from thesisthemes.com. I have installed the events calendar plugin, but the various calendar pages are all overriding my theme completely.

I have spent some time digging through this forum and have seen various comments about copying and editing php files and whatnot. Unfortunately, I am still lost. I want the calendar pages to be seamlessly integrated into my current theme. Here is what is currently going on:

Home Page: https://www.momslittlemonkey.com
Calendar Page: https://www.momslittlemonkey.com/category/events/
Event List Page: https://www.momslittlemonkey.com/category/events/past
Single Event Page: https://www.momslittlemonkey.com/2010/04/full-moon-yoga-retreat/

It doesn’t seem right that this plugin would completely override my current theme. Is this a problem specific to Thesis, or is it caused by running a Thesis Skin?

I would GREATLY appreciate some help in resolving this problem. Thanks.
