Hey Ricky,
Very often, problems like these are related to corrupt user directories. This also seems the case for you.
Of course you can use the new account from now on, but as this is a completely new and clean account you won't have access to your e-mail and other user related things such as saved passwords, Safari bookmarks etc... You also won't have access to any files stored in the User folders of your original User directory (Movies, Music, Documents etc...).
Fortunately there is a way to fix the directory of the old user account. This will probably also fix the issue and you will be able to keep using your existing account. The procedure is very easy, just follow the instructions in the PDF that I have put on my DropBox drive:

NOTE: I have written these instructions for Mavericks, but a lot of people have confirmed that they still work with Yosemite. The only difference is that if you are on Yosemite you probably won't get the warning message in the last step.
