Mail drops accounts on quit

Question

Hi
I am having a real problem with Mail.
Everytime I open the app, I get the "welcome to mail" setup dialogue.
I proceed to set up my gmail account and it all works fine until I quit.
On reopening the app I again get the "welcome to mail" setup screen.
I have tried all the advice seen on these forums like moving various mail files to the desktop and restarting mail but the same problem returns everytime.
Is there something I've missed?
Also my iCloud bookmarks are not loading into my Safari...related problem maybe?
Any suggestions?

Problems such as yours are sometimes caused by files that should belong to you but are locked or have wrong permissions. This procedure will check for such files. It makes no changes and therefore will not, in itself, solve your problem.
First, empty the Trash.
Triple-click the line below to select it, then copy the selected text to the Clipboard (command-C):
find ~ $TMPDIR.. \( -flags +sappnd,schg,uappnd,uchg -o ! -user $UID -o ! -perm -600 -o -acl \) 2> /dev/null | wc -l
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
The output of this command, on a line directly below what you entered, will be a number such as "41." Please post it in a reply.
