Reading through the description of the system it is quite obvious that it is not suited to multiple access - particularly the deletion and re-insertion of data rather than updates.
There is no manner in which you can 'fix' things that will not cause you a world of pain in the future.

I would say you have 2 options:

(1)Rewrite the underlying database update mechanism so that it does not makes use of deletions and inserts.
(2)Leave things as they are an only allow one user to access the application at a time.

Even if you do go with option (1) there is no solution to the update conflict issue.
Quite simply if two users grab the same record, the person who makes the second update wins - there is no way around this no matter how much clever code you write.
Given that the best minds in computer science have not yet solved this problem there is little chance that you or I will.
