Modpack coremods is a file instead of a folder

[KaBombz]

So I've set up my modpack and everything, I've gotten it to work, but whenever I launch it FML gives me an error. Here's the log.

2013-04-12 10:33:24 [iNFO] [sTDOUT] Exiting mod pack

In my pack directory, I found that instead of a folder, coremods is labeled as "File". If I delete the file and create a folder with the same name, the modpack works fine but ChickenCode Core and NEI don't launch because they were in the coremods folder of my modpack zip. I really don't know what to do here.

Bump, someone please help. I'm still stuck and I've been through like every google search possible.

[D3matt]

Have you tried remaking the folder and putting the mods back in the folder? Obviously if you delete it they aren't going to magically to reappear.

I would recommend another visit to the rules page, for your own good. ;)
