To repair this we're going to put two folders on your server out of commission by renaming them and then delete two records from the DataBase (DB) of your broken site.
Using Cpanel's File Manager or your FTP client:
RENAME ..\libraries\rokcommon TO ..\libraries\rokcommon_OLD

RENAME ..\plugins\system\rokcommon TO ..\plugins\system\rokcommon_OLD

Now login to your Database with AdMiner or PhpMyAdmin and search your DB for "RokCommon"

Now we go to the Extension Manager screen to Upload our Package files. Again disregard the error messages. If you have both RokGallery and RokSprocket on your site, install the latest version of RokGallery and THEN the latest version of RokSprocket.
