Dolphin 7 Beta 2 error

I tried installing the new dolphin 7 beta 2, but I have this error:

Fatal error: Call to a member function getFilesUrl() on a non-object in /home1/mysite/public_html/dolphin_test/modules/boonex/sounds/classes/BxSoundsSearch.php on line 52

Does anyone have an idea how to solve this? Only have the error on a white page..

Thanks

Also, when I edit the advanced settings in the admin panel, I get this one:

Warning: getimagesize() [function.getimagesize]: Filename cannot be empty in /home1/mysite/public_html/dolphin_test/inc/classes/BxDolAdminSettings.php on line 362

Warning: Cannot modify header information - headers already sent by (output started at /home1/mysite/public_html/dolphin_test/inc/classes/BxDolAdminSettings.php:362) in /home1/mysite/public_html/dolphin_test/inc/admin_design.inc.php on line 54

This is a PHP error you probably need to check the compatability list.  It sounds like you may have allow_url_fopen option in your php.ini set improperly. Check with your hosting provider.

Thanks but that didn't work.. Any other suggestions?

Hello TruckingSpace !

First problem will appear when you try to install new Beta package on the same place as previous. In this case you just ovewrite files, so old cache inc and php files in cache directories haven't been cleared. You should clear cache and cache_public folders or install one of any modules.
