I recently installed the MVP 2015 Mod over my MVP 05. I did all the correct procedures including using a fresh install of the game as well as using all 5 patches. However, when I go to install the mod via the "explodeme" unpacker, there's 15 files that receive the message "cannot open output file". The 15 files that receive this message are all .dat files and are all in the same folder. The file names that receive this error are, in order: lhattrib, lhbstats, lhpstats, manager, org, pitcher, pstats, rhattrib, rhbstats, rhpstats, and roster. As stated before, these are all .dat files. I launched the game anyway and sure enough the rosters were missing, alone with everything else that received the error. If someone could help me out it would be greatly appreciated. I will also attach a screenshot of the diagnostic/error box.
