Hallo STEPforum, this is my first post in the STEP forums so let me introduce myself: just call me BUBISHI, this has something to do with my other hobby - who can guess? After I have bought a new PC one year ago I wanted to continue my somehow bad experiance with Skyrim on PS3. But someone convinced me to give moded Morrowind a try and I got in love with this beautifull game. I used MSGO and added lots of mods later manually, but I never got the deep understanding of how all the small gears work together - I learned to use Wrye Mash, TEStool etc, but allways kept to written instructions. I also never tried to create mods myself. Now it's time for me start Skyrim, and a user in the Bethesda forums suggested STEP. I wanted to stert with a optimazed, fully patched and RP-moded Skyrim and think STEP is a great tool for me. Now as I'm not an native speaker and the STEP guides are fairly comprehensive I find it hard to get through it. Here my problem with DDSopt: I have completed all the steps to optimize the Vanilla Textures and have placed the zipped files in the ModOrganizer directory. Then I have manually installed the archives from ModOptimizer. They appear in the left pannel as installed mods. Now the STEP instruction says: I should uncheck the last three checked files in my plug ins window, right? If YES it should be like this. But now if I try to start the game with my only test save I get a warrning missing mods text message, the errors can be seen in ModOrganizer iif i inspect the save. The save misses the three deactivated esp. I must have done something wrong and need advice here. I have also made screenshots of the Data in ModOrganizer and I see the optimized replacers. Here also a look into the Archives pannel. Do I have to uncheck files here? I have also read that I should delete the replaced files from my games/Skyrim/Data folder. This seems strange as I always though ModOrganizer never needs to make changes in the Data folder. If I should delete/replace files in this folder, could someone confirm that and point my to those files, please? I belive I'm not the first with this problems, but reading the other topics and guides did not help me much. Thank You for reading about my problems, maybe You can help me.
