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?

If this problem is project-independant you should reinstall STEP7 (probably on another computer). There you should save project with reorganization. Everything must be ok after that,

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.

If you didn't do much in that project (I suppose you have a very good backup) then please try to start a new project and see what happens. If it is then ok, the project is damaged that much that reorganizing won't help any more. If you have good contacts to Siemens then you may ask (if your backup is not so up-to-date) if they could repair the project. Normally they could repair some more, also a newer version of STEP7 would repair more then an older version. If STEP7 only creates damaged projects {please look very well to the resources of your computer} then the only way is to deinstall STEP7 completely as mentioned in the FAQ and install it again.
	I hope that the answer will help, if you have still questions, don't hesitate to ask me. All the best, Late Never say never, think in solutions, not in trouble......
