Your ATPL exam credits are still valid. Theory exam credits never expire - they 'remain valid for' - there is a subtle difference.
Exams are downward creditable, so as written the ATPLs remain valid for:
LAPL/PPL - 2 years
CPL/IR - 3 years
ATPL - 7 years (rolling)
FIight Instructor/ 1st MP type - indefinitely.
So in your case you cannot use them for IR (because it's been more than 3 years) but they technically remain valid for the ATPL because you have a CPL/Type.
