Installing mods in tekkit lite results in grey window

[Eegxeta]

I'm trying to add some mods to tekkit lite, but I can't get anything to work all I get is a grey window after the FML has done its thing and it just sits there. I have just put the zip or jar in the mods folder and I have tried adding the files in the zip and jar files to modpack.jar which doesn't work and I have tried transplanting the mods from another modpack that didn't work. Yes I have looked at the sites to download these files. I'm clearly missing some piece of info or doing something wrong but I don't know what can somebody a little less clueless help me?

The mods I want to install are advancedsolarpanels, ExtrabiomesXL and DynamicElevators. I also want to update MineFactory Reloaded to the latest version.

Edit: Just dropping the stuff into the mods folder crashes minecraft.

Ok I figured part of it out. Note to self read crash reports before posting.

Ok how do you make minecraft automaticly give a new id to a block when there is a conflict?

Use ID Resolver if you want automatic resolving of ID's. Otherwise, you'll just have to resolve stuff manually. Making a NEI item dump to see all the free block ID's can help.

Forge seems to be able to work with some mods and shift IDs around automatically on its own, at least that is what I think it was doing, but yes, most of the mods need their configs hand-tweaked.
