"I can't open my database, when I try to open the next message appears, Could you help me I need to open: 'Name.mdb' isn't a index in this table. Look in the indexes collection in the TableDef object to determine the valid index name"

Did you try to repair? BTW there's an updated Jetcomp utility, available at
the M$ web site. What's different about it is that it doesn't try to open
the database first before it does the repair, so (supposedly) it has a
higher success rate. If that _still_ doesn't work:

Create a new empty database, and import all of the objects into it. If one
of your tables is trashed, it will stop at that point, and at least you'll
be able to identify the source of the problem. If this is the case, import
everything _except_ that object, and then re-create it. That's better than
starting from ground zero.

If you can't import _any_ object from the old into the new database, it's
time to restore your backup. Either that, or hire a data recovery team, you
can find them on the web.
