Looks like I'll have to wait for V3. All I get is an error box that pops up saying:
ptpCamGui 2.0.97 - Error
Different Versions: Current (supported)
ptpcam: 1.0 (2.0)
camera: 1.0 (2.0)
[edit]
Nevermind, I see that the ptp protocol was updated in revsion 1155 on the trunk-log. Downloading a new CHDK now.... (if it gets here).

Well, that was no fun. Now all I get is:
ptpCamGui 2.0.97 - Error
Different Versions: Current (supported)
ptpcam: 1.0 (2.0)

After reading google translations of the German forum I find that this is caused by overwriting the old files with the new. You have to install v2x into a new folder.
Now I'm back at square one, all I get are continual strings of (ignore typos, typed these by hand from reading the little console box, it no longer allows you to copy from it):
>> luar get_model() << script:65
65:ret:false (Length: 23)
>> luar get_model() << script:66
66:ret:false (Length: 23)
>> luar get_model() << script:67
67:ret:false (Length: 23)
>> luar get_model() << script:68
68:ret:false (Length: 23)
Etc.
I think I'm done testing this, nothing's changed, nothing works, and there's too little information to get past all the problems with trying to get it to work.
