Can't download base installer

Purhased 737NG last night and received confirmation number and password to access base installer but, no luck in downloading from link given in my email. When I click the link it says 'page not found'. I"ve tried a number of times over the last 12 hours or so, including in the middle of Sunday night (1:30 am PST). All with no success. I checked earlier messages in this forum and it seems some folks had this problem back in early July-possibly related to high download activity, but is that really still the problem now and at the times I've tried to download?Tried contacting PMDG tech support but no response yet (possibly due to the weekend, although they replied quick enough last night when I purchased the product and sent me the email confirmation and password, so someone must be there).Any help from PMDG or anyone else appreciated as I'm keen to try out the plane and the new FS2004 Service Update.Thanks
