Rave Reports stopped working

Practice




Rave Reports stopped working in all reports and in all versions of the program/
1.I haven't reinstalled Delphi
2. I haven't changed any settings
3. Reports aren't recreated in Rave Reports, neither on new creation nor at program startup
what could the problem be?
Didn't you change anything in the database structure, especially the column data types?
Yes, I did...
I changed a lot of fields that stored dates as Date into DateTime fields
maybe some other changes too
but after rebuilding the original structure, all the reports worked in all versions of the program
there are also sometimes problems with duplicate names in Rave Reports
the RvDataSetConnection component for linking data
an error occurs in all fields - values (invalid)
