1. Extract the patch to the top level folder of your default game installation and run it from there. 2. Don't install the mod until you've patched the game. 3. As long as you abide by the site rules, you will get help.
You can only install the patches to the default version of the game. If you have modded even one file and then try to install the patch, it will fail and tell you that you do not have the default version of the game. Do not extract the TC10 installer to the same folder where you want to want to install the TC mod. Extract the TC10 installer to a different folder (for example TC10_install). When you run the installer and it asks you where to install the mod, THAT is when you specify C:\MVPMods\TC10. Also, regarding your two consecutive messages above, please do not bump your posts to get it moved to the top of the list. That is a violation of forum rules. You need to be patient. If someone has an answer to your question, they will post a response. In addition, the site has been up and down over the last day, so that is why you didn't get an answer sooner.
On Windows-7, I think it installs the game in the "Program Files (x86)" folder by default. That should work. I was only saying not to do that because I remember KC posting that in his post describing how best to install the game.
You don't reinstall another copy with the discs. What it is saying is that you install a clean, unmodded, version of the game once, install any of the official EA patches to it and then NEVER install anything on top of that original version of the game. Whenever you want to install a conversion mod (Total Classics 10, TC1927, MVP15, etc.), you create a new folder and then copy everything (all files and folders) from your "clean" installation folder to your new folder. You then install your conversion mod on top of that new version. For example, I have Windows-XP and have my original copy of the game in the C:\Program Files\EA Sports\MVP Baseball 2005 folder. It doesn't matter where you install the original version, however, if you are running Windows-7, it's best not to install it to the Program Files folder. It's better to install it to a folder like C:\MVP Baseball 2005. When I wanted to install Total Classics 10, I did the following: I created a C:\Total Classics 10 folderI copied everything from C:\Program Files\EA Sports\MVP Baseball 2005 to C:\Total Classics 10I went to the folder where I saved the Total Classics 10 mod and ran its installer.When I was prompted to enter the folder to install the mod, I selected the C:\Total Classics 10 folderWhen the installation was finished, I now had two installations -- the original, "clean", version and Total Classics 10. I repeat steps 1 - 4 above every time I want to install a new conversion mod.
The Cooperstown Effect was already turned off when I ran into this same problem with the Oakland County Coliseum. I just rebuilt the models.big file with the BigGUI utility, like we had to with MVP14, and now the Texture Issue no longer occurs and the field looks fine.
