Shakmah, I know the importance of ensuring you're able to download the latest and greatest software! I researched this for you and found that according to a Microsoft; this error code 80188308 is a result of running out of storage space during the update. Here is the link provided to ensure space is freed up so your phone will allow the update process to complete: http://spr.ly/6581BBqQb. Thank you and please keep us posted on this.
