sql update error

Hello!

first of all sorry for my simple english....

We used 0.1-beta2 (I seen it in the index.php) and today I try to upgrade to roundcubemail-nightly-20070318

When I tried to update mysql I received this:

office SQL # mysql roundcubemail -u root -p < mysql.update-0.1a.sql Enter password: ERROR 1060 (42S21) at line 5: Duplicate column name 'ip' office SQL # mysql roundcubemail -u root -p < mysql.update.sql Enter password: ERROR 1062 (23000) at line 4: Duplicate entry '7-INBOX.msg-437' for key 2

Round cube seens to working but I cannot send email. I dont get an error. The sender combo box is empty.

I am not an linux/database expert.

Can anybody help me? What can I do, and how?

Thanks
