[Koha] Need MARC record database help

[Shane Skeens]

hi all,
we just set up a KohaExpress 3.0x installation through LibLime, who is hosting the installation.  we staged & imported a list of MARC21 records, which showed up fine in the database & OPAC.  we then "reverted" the record import because we discovered many duplicates in the list & wanted to import an updated list.  after the "undo" (done through the administrative backend & "Undo Import" button), the records still appear in searches on the OPAC & backend, but the links return 404 "page not found" errors.

we have re-imported the first list & tried to "revert" it again, but the items were duplicated in the database, as though it did not detect the existing (broken) record-references.  additional "undo" attempts have yielded the same results.

there are no items entered yet.  is there a way to purge (erase) the entire database so we can start over?

we do not have access to SSH or a command line, so we can not use any command options or see the database files themselves.  any help is greatly appreciated!  
thank you!

shane
