Getting Rocketed

Mildly bummed.  After looking at several sources for an Italian course, I finally settled on Rocket Languages Italian, as it has numerous high recommendations from people who've tried other places.  Of course, they always compare it to Rosetta Stone, which has apparently not improved its interface or its style for years, and to DuoLingo, which is good but incomplete.  I also tried people's personal efforts, being impressed with 30 Minute Italian -- only to find that while the content was good, the author had the tendency to say OMG during my last trip to the south of Italy it was just so gorgeous, you have to go. So, I took the plunge with RLI.

Well.  It's possible that I don't understand how to use their site.  But here's what I sent off to them after four hours, off and on, there --

I just started today, and I have a number of questions.  Most relate to Rocket Italian, very first lessons. Overall, this is a very rocky start!

1) The Rocket Italian first lesson seems to have a typo -- it asks for AND YOU in the informal tense (e tu), but E LEI and CIAO are also shown as acceptable.  Surely not!  (note: E LEI does mean 'and you', but in the formal tense, while CIAO means 'hello' or 'goodbye')

2) Trying to left click or double click an icon (see it, hear it, write it, etc) does not work -- I have to right click OPEN LINK AS NEW WINDOW to get the options to work. Is that normal?

3) The Playback (to hear my own recording) button disappeared halfway through the second lesson -- (still there but grayed out and nonselectable) Is that intentional?

4) How many words do you have to do on each section?  I keep doing them until I get tired, but there is no indication of when a section is 'done'.

5) How does the score counter work?  Mine went past 900, then I scrolled backwards to see what the scroll did, realized it was showing me yesterday (I bought the package today), scrolled back, and suddenly it was about 347.  What?

6) how can you tell what your current lesson is? I would expect that there's a 'latest lesson you've done' indicator, but I don't see one. Does one exist?

I'm hoping they have reasonable and quick responses. Otherwise, I'll be seeing how well their guaranteed refund if not satisfied works.
