Problem: When I try to load a file into Tecplot 9 I get this message: Binary file version newer than tecplot version. Upgrade Tecplot or use an older preplot to produce the data.
Solution: The binary file format has been changed with Tecplot 10. If you save a binary file from Tecplot 10 or create a binary file using the current TECIO then try to load the file in Tecplot 9 or an earlier version you will recieve this message.If you open the binary file in a text editor the first characters indicate the version. If it says #!TDV10 it is in the Tecplot 10 format.
