I was not able to install full version because it said download id was not set.

I installed free version hoping when inserted download id i could do it, however, i get this error message

1060 Duplicate column name 'host' SQL=ALTER TABLE `yvd20_sefurls` ADD COLUMN `host` varchar(255) NOT NULL DEFAULT '';

I had previously installed joomsef and then uninstalled. I think this is causing the errors.

Please help.
