If it's the same problem, there is a BIG base problem!
Linux32, Linux64, Windows32, Windows64, MacOS, PlayStation, etc. people cannot interoperate because of the different calculation method used by each compilation (?!). May the source code be more near the standards?
Who compiles Glest by itself, I suppose then can't play with anybody (because of compiling for i386, i586, i686, or with other options) without deactivating the binary check.
