When adding a new language and canceling the childform from the "Open a Messaging Project" form, will throw this Exception and will not let you add another language:
Exception There is no snapshot for the specified key.

See the attached screenshot to see where to add a language as Trent described ealier. You will:
1) Click on Project Settings
2) Click "Add" under the Languages section
3) Select your language from the "Language Properties" box.
Is that the process you are going through to add a language? If so, are you on the latest build of StrataFrame? (I tried in on my end and it worked without issue.)
Thanks!
