product registration

I am having difficulty with the product registration. I seem to be typing the letters and numbers incorrectly because I am having trouble identifying the following character in the series: ll
I type it as a lower case L, does not work, I type it as a misprinted 1, does not work.
HELP

did you try capital “I” ? some fonts l = I
just a thought

Yes, I tried capital L, I tried lower case l, I tried number 1.
It may also be that 0 and O are confusing.

heh, I didn’t mean L, I meant capital “eye” lol which looks the same as lowercase “ell” in this font for instance.
