Spell and Grammar Check not Working office 2010

Please help me. I recently installed MS office 2010 on win 7, and I found out the spell and grammar checker doesnt work. When I entered a wrong spelled word on Powerpoint or Word, it doesnt recognize it as a wrong spelled word.
I looked up on the add and remove features of ms office 2010 and found that the proofing and spell and grammar check are all installed. What should I do? And one more question. How do I reset Ms office 2010 on its default preferences?

In one situation I accidentaly clicked on ignore all when some words are misspelled. Now, no words appear as misspelled(wobbly red line for spelling and green line for grammar doesnt appear anymore). Maybe it is the cause?

Thanks for the reply but I dont have the "override" directory. I only have "custom dictionaries" and "office". I cannot find "override", what should I do.

Thanks for the comments guys, I just solved it. It is just in the proofing language. Mine is Filipino so it cant detect wrong spelled words
