Internal Data Structure error

Dear All

whenever I am opening my new S7 project(CPU-315 2dp), a message window "INTERNAL DATA STRUCTURE ERROR" is coming.

I have gone into the help coming with above message and followed the steps as required
To Correct or Avoid Error:

1.Close all STEP 7 applications except the SIMATIC Manager.

2.Use the menu command File> Save As and the "With reorganization (slow)" option to create a copy of the project, which you can use to continue your work. However, this copy may not contain all the data from the original project because of the defects in the existing project.

But eventhough message is not going.

Pl note that my project is working normally on S7 -Simulator without any problem.

Will above message can create any problem when I download the softwear to CPU?

Asimilar problem happened in one of my projects. I continued working the project but there were two problems :

1. whenever I tried to change hardware, project stucked. but I installed hardware and it worked .

2. some of the cross references, network descriptions showed wrong.

so I kept working but in the end I saved with reorganisation and it worked ok also.
