Delphi form won't open

Just open my IDE (Delphi XE5) to continue coding and I got an error (never experienced similar error !) on creating one form, due to field not found on a Tdbedit. Checked the Table is OK and so the field. Having no access to the form I am almost stump as I cannot edit the form. Before destroying the unit to start from scratch, as the form re-design would take time, can someone give an hint at least how to preserve the form drawing ? Thanks
