Can't reinstall Forge

[Dadwithnoidea]

My son had Forge 1.7.2 working properly and recently when adding some mods that didn't work I have deleted something that I shouldn't have - not sure what I did.  When we launch Minecraft 1.8.1, we still have the options to launch Forge profiles, but when I click on one Minecraft closes.  I've tried to delete all .jar executable files and reinstall Forge, but I can't seem to get it to launch. 

 

What do I need to do to get Forge up and running properly again? 

 

Thank you...

Yup that error is listed in the EAQs, you should really read them.

Update to at least 1.7.10.

[Dadwithnoidea]

Thanks for your help and sorry if I sound dumb as this is all new to me.  :-[ The problem started when I tried to update to 1.8.

 

I have installed both the .jar file and the .exe file, however when I start Minecraft (under the new Forge profile for 1. it opens like a normal Minecraft session and doesn't give me the option for the mods.... 

[Dadwithnoidea]

Sorry, don't know how the sunglass emoji got in there... should have read 1.8 (which I created).  Have also tried the one for 'Forge' and neither work

 

[Ethan Weegee]

This happens to me when I use the latest version. Try the recommended version:

Win-http://adfoc.us/serve/?id=27122855652208

Java-http://adfoc.us/serve/?id=27122855652210

[Dadwithnoidea]

 

This is the only log I can find as it doesn't come up with any error messages, it just opens up the standard Minecraft start screen.  I have tried removing all of the mods from the mod folder and placing one in at a time and trying to open with only 1 mod in folder, but it just keeps coming up with the standard Minecraft start screen.  It's like Forge doesn't exist....
