converting old entities to binary...

am i correct in assuming there are multiple versions of "convertdata.exe" (besides vanilla vs entrenchment)? as in the converter for 1.05 was different from say, 1.1's? if YES, how can I get ahold of the older version, as I am doing personal edits for 7DS and want to binarize my entities. if NOT, why is it that forgetools 3 convertdata binary entities cause sins 1.05 to minidump when my txt entities work just fine?

if anyone has this old 1.05 convertdata, assuming it even matters/exists, could i please get a copy? thanks!
