I've always wondered what would happen if I ever had to change my email, and whether the sign-in spaces for email actually
pinged the email typed in to see if it was still functional or the same as the one actually being used, or if it was simply a pre-
password space like your secret passwords, but not actually requiring a still functioning email.
I haven't downloaded P3Dv4 or it's parts for some time, but when I went to the LM store, there are two ways of getting to getting
to your purchased downloads. On the right hand side are the usual spaces for e-mail and account password, but on the left hand
side are spaces for License ID and License Password. Do you still have those? I used those and it took me directly to the P3Dv4
downloads. I use IDM (Internet Download Manager), which can be set to download to where ever, and it looked like I could just
use IDM to download. There didn't seem to be any specific e-mail login required through License ID and Password.
But going back to what I said earlier, have you tried just typing in your old email address in the Customer Account email space,
and your account password, and seeing if it worked? As said, I don't know if the LM site actually pings that typed in email to see
if it still works or is the same as the one being used.
Sorry, just some thoughts. I don't know if any of this is useful or not.
