I have installed ss using WAMP on WindowsXP.
After pointing my browser to http://localhost/SilverStripe/ I see the initial ss welcome screen.
However, when I attempt to open CMS (even after placing "Security::setDefaultAdmin('hope', 'temp');" in mysite/_config.php, I still get the error:
[User Error] Couldn't run query: SHOW FULL FIELDS IN `Member` Can't create/write to file 'c: emp\#sql294_d_0.MYI' (Errcode: 22)
POST /SilverStripe/Security/LoginForm
Line 400 in C:\wamp\www\SilverStripe\sapphire\core\model\MySQLDatabase.php
I have attached the full trace info.
