Its been 4 days and my THEMES still don’t work

Hi,

I hope someone can help me. I’ve been trying for the past 4 days with frustration to install 2 themes I bought. I was successful in installing the first one through Filezilla. However I had to delete it because I touched something with the code, and now, I cannot get it to reinstall. The second theme is completely hopeless and wouldn’t even install the first place.

My background: I know nothing about HTML and CSS and all that stuff.

I’m just pushing buttons and seeing what works. The themes are clearly visible under “themes” when I look in the folder via Filezilla. However, they don’t show up in “themes” in WordPress. Moreover, when I try to just go through WordPress to upload them it doesn’t work.

Please help. I’m down to my last breathe.
