Help installing Frame Market

Hi,

I am new to this world. I just installed Marketpress and its notification system. I am now trying to install FrameMarket but am getting this error message - any ideas:

Unpacking the package…

Installing the plugin…

Destination folder already exists. /home/content/88/7817288/html/wp-content/plugins/framemarket/

Plugin install failed.

Thank you!!

Lisa
