My adobe after effects closed suddenly.

Hello,
I am having problem with my Adobe After Effects. I experienced for some point in time a message telling me that it is unable to obtain the user language. Is it something to do with the registry key?
I am not opening my registry editor because it might cause severe damage to my computer if I done wrong with that.
You help would be much appreciated.

After Effects error: Crash in progress. Last logged message was: <62344><ASL.ResourceUtils.GetLanguageIDFromRegistry><0> Unable to obtain the User ‘Language’ registry key at: SoftwareAdobeAfter Effects10.0.1 Defaulting to ‘en_US’.
Thanks a lot in advance.
