[ic] trouble launching store

[paul]

hello all--

i just modified a demo store (interchange 4.8.1)
pre-installed with cpanel 4.0. the payment gateway
is verisign. i checked the verisign account manager
and the payflow link is live.

after entering the verisign account information, i
"successfully" launched the store but it doesn't
work. it pretends to process orders but nothing
reaches the payflow link. and now, to make matters
worse i get a "network i/o error" when i click
on the check out button.

if you can help me resolve these issues i'm even willing
to pay!! (since i'm a dumb designer who is in over his
head)

thanks
