403 problem plus website won't load

Hi everyone,
I want to start of by saying I checked the forum for recent 403 problems, but am ashamed to say I did not understand the answers given, about deleting index files and changing ports...I use indexhibit studio to upload new work onto my portfolio as I have been shown to do and yesterday, just after I deleted the current image on my front page, I tried to upload a new image and got the dreaded 403- You don't have permission...etc message. On top of that the site stopped responding and when I checked my website it also refused to load.
Does anyone have any tips as to how I can fix this?
Many thanks from a technophobe!
