If you click on the date year for the TP copyright, it will show you the credits page which shows the version of TP you are using. Plus, having developed TP for the last couple of years, we know that the internal mod version for TP 1.0 is 1.107. Which means you are a couple of versions behind.
To fix the overlapping text you'll have to adjust the CSS.
In index.css find this section:
#footerarea ul li.copyright
Change the line-height to 1.
