Accounts reported incorrectly on my credit report and disputed them

You have a great web site and I appreciate the information I found here.  I had some items being reported incorrectly on my credit report and disputed them.    When they reported these they dropped my credit score by over 80 points.  They did remove the items, however it has been more than thirty days and my credit score has not gone back up.  I thought my score would go back up immediately when this was removed.  Do you know how long it should take for my score to go back up.
