Pittsburgh Uni. 1st Yr Polish. HELP

Oscar E Swan, First Year Polish, University of Pittsburgh.
I read a recommendation for this internet based series of pdf files and, from what I can access, it is exceptional! However, when I attempt to access the 'LANGUAGE DRILLS' there are entry requirements (e-mail address, password etc).
I was under the impression that this resource was free.
If anyone could explain how I access this area of the site I would be eternally gratefull.

what site?

I don't know how to post web links BUT
1. Go to Polish Forums, general Polish language.
2. scroll down to 'Polish language learning links' by hal201 (?)

It's his first recommendation and he's included a link.

The drills are kind of tricky to use. First download the drill zip files to your computer. Then click on the launch lektorek at the top of the page. (or download the lektorek file to your computer if you don't want to use the drills online only). When lektorek is open, click file then select open drillbook. This will load the drills into lektorek and then you can start using them.

By the way, when the lektorek ask for name and e-mail, that's all it asks for. It doesn't ask for any other information from you.

Actually, sunbreak, I believe my initial problem was due to not downloading the Java programme that is necessary to access the drills.
I have not yet returned to retry but I'll make a point of doing it soon.
