The help file says I should try to recompile, but compiling is impossible.
Compilation stops when reffering to DAO objects like

     Dim rcs As RecordSet

The problem started when I desperately (to correct an 'unexpected error')
exported, deleted and reimported all modules.

Sounds like you have some missing references.  Open a module in design
view, from menu choose: Tools>references...

Select any libraries that show as "missing".

Steve

Well these are the selected libraries:
-Visual Basic for Applications
-Microsoft Access 8.0 Object library
-Microsoft Word 8.0 Object library
-Microsoft DAO 3.5 Object library

It's not possible to uncheck: "Cannot perform this operation"

Any ideas?

Dag

You may need to check your references.
Open a module in design mode and click on the tools menu, then click on
references.  Make sure you have an entry saying Microsoft DAO x.x Object
Library.  Also, if any references are prefixed with "MISSING:", uncheck the
check box corresponding to this entry.  
You'll be all set.
