Whenever I go into My Minecraft, it doesnt read the Mod, so when I clicked on the mod file, it said it was invalid or corrupt. Can someone help me.

 same happend to me. I did a bunch of file moving and testing = corruptfile = download again, get a good DL worked for me. 

 I've tried downloading again and it was still a corrupted file!!!

Eh, what the hell are you even trying to do? You're not supposed to open the file.

 He said it also doesn't read the mod when he runs the game.

 Doesn't read the mod eh, uninstall it then reinstall it, make sure you put it in your .minecraft mods folder, check to see if you are playing in the correct version of minecraft, and make sure you are using the correct version of forge, if this doesn't work then you're out of luck

 I just want to point out you don't have to put it in .minecraft, if you want you can run the game out of a different folder. Helps when you want to play on different mod versions easier.

Heres what I find strange. I swapped the Dalek Mod U46 for U45 and it read that version but when I put U46 back in it didnt work!!!

NEVER MIND!!! I HAVE FIXED THE PROBLEM!! CASE closed...
