home in layout is missing

Please can someone help?

I'm not sure how this happened, but my modules on the home page just disappeared and when I went to the Layout section in ADMIN I saw my "Home" layout was gone!
I tried creating a new one with the route being"common/home" but this is not working, do I have the route incorrect?

I am using mutiple stores so the layouts for each store is different.

Eg.

"Home" is for the default store
"Store1:Home" is for Store 1
"Store2:Home" is for Store 2
"Store3:Home" is for Store 3

Thanks in advance

Okay, I've reinstalled OC and everything was going well and again, after I added the 3rd store the modules on the default page which were set to "Home" have gone, none of the modules will display with the "Home" layout.

This time however the "Home" is still visible in the Layout section.

Anyone know what I can do to solve this?

I'm using v 1.5.1.3
