I think we reissued the same version of a DLL either for testing or a last minute fix on something, but didn't change the version #. (It happens sometimes.)
If your ephinea.dll is 8,985,600 bytes with an MD5 of 176f391cf9af5685c0d355fb7e98be80, then you're good.
(Can figure out the MD5 of a file by dropping to a Command Prompt and typing "certutil -hashfile ephinea.dll MD5" while in your Ephinea folder.
