disappeared blog after upgrade, complicated–using dreamweaver,

hostgator host–
had a great blog–
but everytime get message that i need to upgrade there’s a real jam–
ftp is dreamweaver,
have control panel on hostgator,
and the message is there that i need to perform, when it’s time to, a “manual” upgrade.

so i try to follow the instructions–even the detailed ones.
i backed up my mysql database
i backed up the folder that had my blog
etc
then i tried to upgrade this way:
i downloaded to computer 2.6.2 (had 2.6.1 already running)
i threw out all that i thought i was supposed as directed on the support instructions (wp) (from 2.6.1) except
i saved my themes and plugins (after inactivating them thru the wordpress admin site)
i savved the files they told me on the instructions from wp that i had printed out
well,
when it came time to upload the upgrade folder,
well, i forgot until this time again,
you can’t upload a whole folder to hostgator thru cpanel.
you have to do it one little file at a time (document like) and thru their panes which is like filling one grain of rice at a time…
and they only allow 9 files to go up, or so, so to keep track…it’s like forever.
i decided, after a few hours of this, to simply
TRY TO FTP THE WHOLE FOLDER (WP 2.6.2)
up to the blog folder on the server myself

by using dreamweaver and my ftp

which i did
now,
i have no idea where my blog is

can’t get to it by
https://www.example.com/blog/wp-admin
or example.com/blog/wp-upgrade
or no way

as a matter of fact, you can’t get to it even on it’s
web address.

can any one PLEASE ADVISE

thanks

poss problems that i think occurred
somehow the connection between blog and database, and blog and header (?) or placement on
real estate on the server or
not all the things in the right order or in the cohesion needed for wp to work
or
the installer/upgrader isn’t “running” and the webhost or who ever doens’t know how to get it going
or
the database is somehow not connected to the blog anymore
or
HELP!!!
