Recover account info

[Alexander]

I'm trying to get access to my company's account. Previous webmaster gave me login and password but every time I try to log in using them Google says that account doesn't exist.

Feed address is http://feeds.feedburner.com/qtmsoft .

Is it possible to recover account information? Or at least to find out the link that is the source for that feed.

I would be appreciate for any help with this problem.
