Happy Second Posting, Mousie! The errors you show almost look like you are trying to mod an incorrect version of SH4. Did / does the game run fine without TMO enabled? TMO 2.5 was written for SH4 v1.5, which has the Uboat Missions add-on. Do you have a choice for a German career on the Start menu? If you do, which version of TMO do you have? What folder do you have SH4 installed in?
