Hi every bod.

 I have a problem with my program of S5.When I want to open my program. To many error appeared.

what should I do to solve this error?

Please don't post twice for the same problem. You've already created a topic for your problem here:

https://support.industry.siemens.com/tf/de/en/posts/to-many-block-error-in-s5/200714/?page=0&pageSize=10

Since the software you are using is not an original Siemens STEP5, the moderation moved your topic to the Meet & Talk conference.

Thanks so much.

 excuse me.

Closed, because the question was posted twice.

The second thread with the subject to many block error in S5 is published within the conference Meet & Talk.

Best regards
