Hi,
Any bigger bazooka and we will need a MASH tent !!!
Do you have any issues with the Contacts App ?
Is it syncing properly with your iPhone ?
Are you using iCloud or some other method to do this ?
(It can be iTunes or Google, Yahoo or Facebook)
Deleting the com.apple.ichat.plist should have excluded and AppleScript things getting in the way.
In System Preferences > Users and Groups > Your account > Login Items do you have anything listed that works with Messages ? (An AppleScript that relogs Messages in if it drops a Connection)
Open the Contacts app.
Find the My Card. It is the one with the Head and Shoulders icon and should be next to your details.
In Addition activate the Bonjour Account in Messages
Then in the Window Menu click the Buddies item (CMD+ 1)
You should now have a Buddy list on View.
It should also state it is the Bonjour window as it is the only other account you have.
Does it list your name as per the Address Card you looked at ? (on the top left under the Traffic light buttons/blobs).
In iChat if the My Card was wrong iChat would not open properly.
In Messages It is not clear what effect it will have.
Basically the Contacts App/Address Book needs to be working properly to have iChat/Messages working properly.
AppleScript or Automator could have something set up for Messages that is effecting it.
Can you also do the following ?
Have Finder window Open.
Go to the View Menu and choose the Show Path Bar item
Now access the ~/Library folder.
Find the Messages folder with in this
Open the folder.
It should contain Archive and several chat.db items.
Can you click each in turn and do A Get Info (CMD+ i keys together)
Do you own all of them ?
Now Right Click the Messages Folder in the Path bar and Choose Get Info
Do You Own this ?
Repeat for the Library itself.
DO you own that ?
If you highlight your Name and then open the Cogwheel type icon it should be greyed out (You already Own the item.)
It is late where I am and it may be while before I pick up on new replies.
