Hi,
I tried upgrading from 6,1,4 to 6,3 and it simply won't go after the flight check because of "database failure"

Furthermore, I tried to cancel. it then completely screwed the appaerance of the email accounts which now appear like this:
<span>Hairmed Greffe Cheveux</span>

<span>INBOX</span>


<span>SENT</span>


<span>trash</span>
<span>Europe Dentaire</span>

<span>INBOX</span>


<span>trash</span>
<span>Pierre Hollenbeck Esthetic Planet</span>

<b>INBOX(3)<b>


<span>trash</span>
<span>Pierre Hollenbeck - Hairmed</span>

<b>INBOX(4)<b>


<span>trash</span>
<span>Esthetic Planet</span>

<b>INBOX(1)<b>


<span>SENT</span>


<span>TRASH</span>

The word Span is everywhere and the smal icons have disapeared....

Now the upgrade wizard is simply not available, when I click on it ( in order for instance to upgrade to 6,2) the CRM just keeps looping on eth admin page and not moving.
Eventually the page just goes blank.

What can I do to erase the upgrade pack?
Can I go to /cache/upload/upgrades/temp and erase everything?
as well as /cache/upload/upgrades/ ???

thank you for your answer .
