I have been having problems logging into admin, getting a message that I have entered the wrong user name or password.

I have (had) two functioning carts. After much reading in the forum I thought this might be a server or host problem & asked my host to check into it. The immediate result was my carts became inaccessible at all from the front end!

One shows a zen error message
- Sorry there seems to be a problem connecting to our database
the other has this message

1146 Table 'xxxxxxxx_zc1.xxxxxxxx_db_cache' doesn't exist
in:
[db_cache table]
My host's nice CSR emailed me that I have no db_cache file on either cart AND that this table is missing from the backup.... she wants to 'restore' the databases. Since the backup is also missing this table I am assuming she means reload the cart.

This fills me with alarm. Won't this remove everything? All my product?

I am not a programmer. I don't understand a lot of the lingo. My hosting is linux and has a CPanel. Sincerely appreciate clear and simple instructions and or advice to

(1) replace this table in the databases, and then
(2) find out and fix whatever was causing the original access to admin problem.

Thanks
