I made some changes to fields in a table which invalidated a single relationship. Now when I open the solution I get an error message saying the relations need fixing but when I go to the relations to do this, ALL my relationships are gone (I had about 30 created, now none are listed) and I cannot create any new ones. When I click the New button the normal window comes up and I can select the tables and fields as normal but when I click OK the new relationship is not listed.
Loading a different solution does correctly show the relevant relations for the solution.
