very nice work on providing the files, thank you very much, minidumps averted. And sorry to complain about the site, I did indeed think it was a Stardock work.
Ironclad/Stardock have provided the Forge Tools, of which the Galaxy Forge, Particle Forge, convertXSI, the Developer.exe, and convert data tools are all kept up to date (the later two get from your Sins of a Solar Empire folder). The rest of the forge tools like the reference data has not been updated for a long time. The tutorials in them are still mostly accurate but some things have changed, so you're better of using modder created ones.
That said, they will be updating the galaxy forge and possibly particle forge for Rebellion, so they are still doing some things for the modding community.
