If you want to contact anyone regarding steam you have to contact valve. Although I seriouslydoubt it is a problem that serious and can probably be fixed by other means. Uninstalling and re-installing will not help it will probably be something to do with the files that aren't included in steams 'local content'. I have never experienced this error due to my sabatical of fm but my guess would be the error is related to the above.
