Don't panic! It's easy. Go to your menu of LW & the 2nd option from the left should be View menu. It might even have (V) after it. Then scroll down that list to the bottom & select that. That is Change language. Now in the next window you should see english. Choose that. For the change to take affect you need to quit LW & re-open it.
