I can't help feeling something went wrong somewhere, Simatic Panic. Your "trick" is like saying the trick to driving a car is to take all the wheels off, move them round by one position and then put them all back on again. This isn't necessary.
When you do File / Open in Simatic Manager, you should get a dialogue box with 4 tabs: Projects, Libraries, Sample Projects, and Multiprojects. Whenever you install new software packages in to STEP7 (e.g. S7 GRAPH, SCL, comms packages, FM configuration s/w etc), these will always have examples provided which will be accessible from the 'Sample Projects' tab. You can use them from there exactly as you would any other project. Siemens' convention is to name them all with an initial 'Z' followed by a two-letter code denoting the language the example has been written in. RMA referred to this with his 'ZDt' in German, as opposed to 'ZEn'. There's also 'ZFr', 'ZEs' and, my personal favourite,'ZIt' - did nobody ever tell them?!
