Hi all, My minecraft game failed to start. This happened about three days after purchasing and playing the game. We also purchased a new computer the same day so I can't see how it might be the computer. I have pasted the report below because it is jargon to me!!!! If anyone can help me I would be very grateful...

the aether mod is very outdated, you need to downgrade minecraft to play with that mod
HihhiiiHi Webrosc, Thank you for replying so quickly... I'm a bit Minecraft illiterate and am on this sight on behalf of my son. How do we downgrade our Minecraft. Do we need to upgrade or downgrade when he plays with different mods. How do we identify if a mod is an old one or new one??
as your new to modding i would suggest you look at using multimc, its a launcher that does the adding of mods for you (well most of the work) and also has downgrading built in using mcnostalgia
the multimc thread has a few good videos explaining how to use it, and if you look in the tut&faq section here you will find a few guides on mod installing
multimc also has the feature of multiple instances, so you can have a vanilla instance (no mods) and thenn instances with certain mods depending on your sons mood

note the 1.4.7 which is minecrafts current version
as your new to modding i would suggest you look at using multimc, its a launcher that does the adding of mods for you (well most of the work) and also has downgrading built in using mcnostalgia
the multimc thread has a few good videos explaining how to use it, and if you look in the tut&faq section here you will find a few guides on mod installing
