please help immediately

Hello, am a beginner and not too good with this. please i need assistance. using the marketplace plugin,

1 Product page was not auto generated, i cant seem to find were all my added products are. I have tried to create my own page, but still added products dont show there.

2, From the frontend, the writings, (fonts) are not clear. everything is just showing white boxes after i put this code on page [wpmp-all-products imgwidth=250 perpage=15]. And also, when i try to add product from front end, the browse bottons to upload images from the frontend, none of these bottons are working.
