SharePoint 2010 Failed to Upgrade (space issue)

We are running SharePoint 2010 and are using SQL Express.  We just started running into space issues and are planning on converting to full version of SQL. However, in the midst of having space issues we tried running the Update WIzard and it is unable to finish.  Erroring out and here is the error....

 Could not allocate space for object 'sys.syscolpars'.'clst' in database 'WSS_Content' because the 'PRIMARY' filegroup is full. Create disk space by deleting unneeded files, dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup.

Is there a way to free up space (we can't get the site to come up so we can delete files.


The entire error log:
