I currently cant log into my 123 reg account and my domain name will expire soon .. .will I lose my files at my host if i re-register the domain name and then point it to the DNS and will it lose the "oldness" of the site? Thanks again!
If you are using a different hosting company than your registrar, then you probably won't lose your data even if your domain expires. However if your domain is of value to someone else and you let it expire, you might not be able to re-register it because other people might backorder it at drop catchers.
