Error message when uploading


Recently got a dreamhost package.
Ive made my website fully on frontpage.
I’m trying to upload it by going to
file>>pubish site Then i choose the FTP option

From here I can slowly upload my pages. However, when I click and drag a file it uploads it very slowly; it also rarely works if I try to upload more than 1 file at a time. This is a problem when a folder contains 40 files. Is it meant to upload this slowly? It also takes a very long time for it to refresh the remote site location or to list the “subsites”.

Often when uploading I get this error message:

"Microsoft Office Frontpage

500PPORT not understood
500LPRT not understood"

I dont know what this means but I think it might be causing the problem.
