Same here, too - packs not showing up after F5 refresh in the Rapture browser.
Tried both: 32bit (zips copied to program files (x86)/...), 64bit (zips copied to program files/....)
Full Rapture installed fine (used the recent 1.22 patchfix) and I have LE installed as well.
I opened up a ticket yesterday to see if there's a workaround for X2.
