firstly, i have error message durimg restoration, something like "cannot insert duplicate key in dbo.software", i fixed this with editing restoredata.bat (-Dsdp.restore.error.ignoretables=softwarelist).

but now, i have some positions in assets->scanned software list, marked as "[Rendering Exception]", thay can't be deleted (apache error 500), and I can't do any backups now.

how can i fix this problem?
