You can download the build at http://labs.adobe.com/downloads/lensprofile_creator.html. This build fixed several bugs found in the ALPC 1.0 release:
1) Fixed a metadata bug where the camera's sensor format factor (crop factor) was not written to the output lcp files for certain cameras, such as Samsung NX 10 for example.
2) ALPC asks the user to give up the saving the profile if the camera make EXIF contains special non-alphanumeric characters. See the issue as reported in http://forums.adobe.com/thread/650251?tstart=0.
3) Added a preference setting to ignore warning messages when batch processing multiple image sets. This is to improve the automated batch processing workflow.
If you have already created your profile, you should not worry about to go back to re-create the lens profiles using this new version. For new profiles that you want to generate, please pick up the latest release.
