I swapped back to Osu Latest (solved my issues, was my massive GPU overclock)
I run SC and Osu as Admin and I get the same error message.
Upon research on this error, it seems SQLite.dll is only x86 or x64, never both.
I don't know what version you are compiling against nor can I find the version that's actually being loaded (because its apparently NOT the version you are distributing with the program).
I'm running Win 7 64-bit if that helps, I know how finicky SQL can get between x86 and x86-64.
