At some sites, possibly, but overall probably not as long as everything else is the same, the date you joined being acurate is the main thing if thats correct you will be fine. Actually as long as you put the E-mail address you joined the Bookmkaer with on the TGT claim form that will be OK so we know what to be looking for.
If the claim came in from say
rudolf@yahoo.com but at the bookmaker you joined from you signed up as
ucker@yahoo.com that might cause a problem. Put the E-mail address you use at the bookmakers on the form when you fill it in.
