Translators were not loaded due to errors

Anyone familiar with this error I got in DW?

“The following translators were not loaded due to errors:
PHP_MySQL.htm: has configuration information that is invalid.
Spry.htm has configuration information that is invalid.
SpryWidget.htm has configuration information that is invalid.”

I never had errors before but today it just popped up. And I deleted the WinFile Cache-xxx.dat in the DW configuration folder but it didn’t help! :*(
