ICal duplicate accounts

Question

Since I have upgraded to Lion and switch to iCloud my Calender gives me duplicate accounts. No matter what I have done they return. I sick of it. Can any one tell me how fix this problem? I have tried many things that I have found out on the web but they keep returning.

Ok, hereis what I the steps that I have done.
1) Signed out of iCloud
2) Remove all accounts under "Mail, Contacts & Calenders"
3) Cleared ~/Library/Calenders folder
4) Went back and checked "Mail, Contacts & Calenders" and sure enough the MobileMe account had popup again.
5) Went under ~/Library/Cache and removed file that contained iCal - that stop the account from populating temporarily.
6) Restarted
7) Went under "Mail, Contacts & Calenders" and only added my iCloud account.
And the race was on, duplicates again.
8) Created Test account.
9) Restarted login to Test account
10) Added my iCloud account under "Mail, Contacts & Calenders"
11) Opened iCal "No Duplications of Accounts or Events" in Test account. Waited 30mins or so and everything is ok in the Calenders (no duos).
==========================
So here is what I did to try and resolve this mystery (right or wrong)
12) Copy the Calenders folder from the ~/Library folder to the /users/Shared folder
13) Copy the Cache file from the ~/Library/Cache folder that contains iCal to the /users/Shared folder (note: this is hidden file)
14) Logout of test account and login back into primary account.
15) Checked to make sure there are no accounts in "Mail, Contacts & Calenders" and also made sure ~/Library/Calenders was empty.
16) Copied the folder /users/Calenders to ~/Library and the Cache folder (com.apple.iCal) copy it to ~/Library/Cache. If you do not see the com.apple.iCal folder in /users/Shared it may be hidden.
17) Restarted once again.
18) Logged in to my primary account.
19) Went to System Perferences and made sur I was logged into iCloud.
20) Opened iCal and waited.... 2hrs later no duplicate accounts or events. Added some test events and it sync the event than started duplicating accounts again. What a pain in the A$$.
21) back at square one!!!
