Are you just trying to unlink a normal alias?
YES!
I have the same problem on two computers: i can't remove/unlink the alias.
On computer#1 (windowsXP, PT3 3.11.7.0 beta, PartyPoker) i got the message see above.
On computer#2 (windows7, PT3 3.11.7.0 beta, PartyPoker) i got this:

Apparently the unlink needs a cache both omaha (on computer#1 it asks for it, altough i never played omaha) and holdem (on computer#2 there still isn't a populated cache).
A comment: as for the alias i thought it works similar to HM2 (i use PT3, but this feature in HM2 i find really good), i.e. it is possible to have on the player list a screenname, an older nick, and "virtual/fake" player as alias. So i could check a total result (screenname+older nick) or only the result of the actual player (screenname). Creating an alias in PT3 causes that the alias-player (older nick) disappears from the player list. I have created a virtual player (fake hand-import), afterwards i can't set the actual screename, because it is not on the player list anymore. That's why i want remove the alias.
Best regards
