I think you have got access to your database via phpMyAdmin. If yes, follow these steps.
XOOPS_ROOT/themes/default exists and it has all original files what comes with the original distribution.
Then open xoops_config table using phpMyAdmin and look for 'conf_name' is 'theme_set' (most probably 'id' is 7). Set 'conf_value' to 'default' - You are set.
Remove files from cache and template_c directory if required.
Waiting for your feedback
