I've noted that if in the load I don't have ia >> *this; then I get unsupported_class_version when compiling. However, I've also noted that Store creates nearly identical archive files whether it is: oa << this; or oa << *this; ??? the file stores and loads ok if both are with '*', but I'm unclear as to why the boost library creates almost identical archives. The only difference I can tell is one has a newline following the version info. and one doesn't. I recall it is the one with the newline that then won't load. I'll add, the data that is stored is also still suspect as it does not seem to be having numbers I would expect, so I'm going to do more checking tomorrow.

Don't you mean oa << *this and ia >> *this? I doubt that you want a new object created in load, but rather this object loaded from the file?
