Hi Anna,
There is one thing i would like you to check if you a full copy of Crystal Reports. Can you open up the report in Crystal and go to database, set datasource location? When in there at the top of the window where it says current data source can you expand your datasource, then expand properties below it. Do you see inside of properties where it will say "Database:"? The database listed there is the one you should see in Logicity solution builder. The problem I've come across is Crystal will allow you to have a datasource without a datasource saved with the report. If you do not see one saved please proceed on inside of set datasource location to perform a set database and select one from below "replace with". Thanks!
Matt
