If you have mod installation issues, use
MultiMC. I seriously cannot endorse it enough, it makes it easy to maintain different MC installs for different servers and stuff.
Getting started:
- Download the mods used (Forge 4.x, PlayerAPI, TFC, Smart Moving). Put them in the global mods folder (by default, folder named 'mods' in the same folder as the MultiMC program)
- Open MultiMC. Create a new instance (left-most button)
- Click on the Open Mods Folder button (blue folder with a star, fourth button)
- Right-click the instance. Select 'Edit Mods'.
- Drag Forge and PlayerAPI zips (as they come) onto the list area in the Jar Mods tab. Order matters - Forge first.
- Extract the downloaded Smart Moving zip. Drag the TFC and Smart Moving Client for ModLoader zips into the Mods tab.
- Close the Edit Mods dialog and double-click your instance to run. Simple!
Now any time you want to play TFC you have this TFC-installed copy of Minecraft. Just launch via MultiMC and you're good.
Note: If you're concerned about security issues, I've been using MultiMC for quite some time and my account's just fine.
Note 2: I'm pretty sure you can export an instance, but it doesn't export the actual mods used (as in the files), only the settings, so it's pretty useless. You can MANUALLY export it, though, but you can't just import that via a dialog.
