Although Tony often disagrees with me, I very much recommend against trying to open older version projects with newer versions of the program.
It seems to work better with version 4, 7 and 8 projects -- but the program has undergone such dramatic restructuring since version 2 that, even if you get a version 2 project open in version 7, you're likely to run into lots of strangeness and occasional corruptions.
I recommend finishing your version 2 project in version 2. Then start fresh in version 7.
Hi, thanks for the response. The project was actually finished in v2, but I wanted to open it in v7 as a reference. I don't want (and shouldn't) have to keep all previous versions of the software installed on my system so that I may be able to open project files. Most software programs I work with are backwards compatible or provide some means of upgrading files to newer format. Can you imagine how things would be if Word Doc format became unusable with each MS Word release? :-)
In this particular case, Pre7 shouldn't be crashing like it is. Ideally, it should recognize a previous version project file and either update it automatically or drop features no longer supported (with some message to the user or log file generated). The error message is ambiguous at best and pretty useless as it didn't really help in identifying the root cause of the problem. This is likely the result of some uncaught exception when the program parses the .prel project file and finds an element attribute it doesn't expect (version "3" instead of "4").
