When using Siemens Step 7 micro/win v4.0 software to upload plc program from Siemens S7-200 cpu I get "block format not recognised" and cannot view the program in ladder or any other editor. However it looks like the laptop is communicating OK and the program has been uploaded. It just can't be viewed.

Does anyone know of a problem with software versions or any other reason for this problem? The CPU was programmed in 1999 and this software is brand new.
 
can u put more detail out? maybe u can set some little option just like the language, and try.

if u want send the Program to me i want check it. my email addr: NN36 [at] QQ.COM and i am in china
