Test Method option not available in unit testing

[PioPio2]

Rubberduck version information The info below can be copy-paste-completed from the first lines of Rubberduck's log or the About box:

Rubberduck version 2.5.9.6316
Operating System: Win 7 32bit

Description I can successfully create the test module but once done I cannot create any test method because the option is grayed out. if I add one manually then I don't have it in the test list in the test explorer. This happens only to big projects but not in small ones.

Expected behavior The option test method should be available

In the end I solved the issues by creating a new Access file and transfer over all forms, queries, modules etc. No more errors here now.
