*URGENT* Cant visualize Wrokflow rules with Lock

*URGENT* Cant visualize Wrokflow rules with Lock

Hey,

I have two workflow rules with lock. Before the Lock i could open them, visualize them and modify them. Now with the lock whenever I open them it shows me the message:

"Once edited, any changes made will be saved and the Rule will be locked again.
Do you still want to edit this rule?"

Then I click "Edit", and the workflow rule opens but it shows nothing. It shows a blank page, I can't visualize the rule o edit it. 

I attach the screen captures.

We really need to edit the workflow rules with lock, and we can't. We are an organization with 120+ employees on CRM, and we need this to be fixed soon.
