Confirmed, I experienced similar issues - tested with seperate VMs, like Menthix did.
After signing in on the leaked WLM 2010 (using the patch which is being circulated), contacts won't be able to nudge you, send you files/voiceclips/winks or initiate video/audio calls/games etc with you on that account (although you can still initiate games/calls yourself).
This persists even when you sign in with that account on WLM 2009 afterwards, with the error message Menthix posted and the options being greyed out.

I found a way to solve the problem, login with the account affected in iloveim (select the older version at bottom of the page), login again in WLM 2009 and ask a friend to send you a file.
Doesn't seem to work for me. Tried iloveim, meebo and microsoft's web messenger, but the features still don't work when signing in on WLM 2009 afterwards.

same
edit: Tested it with another account, same results.
Conclusion: Signing in to the leaked WLM 2010
will break stuff, even when you switch back to WLM 2009.
