@aediaλ Thanks, really useful. – Afshin Mehrabani Feb 13 '13 at 6:41
Anything with did or did not will keep the infinitive version of the verb – mplungjan Feb 13 '13 at 8:41
@mplungjan Aha, I got it. – Afshin Mehrabani Feb 13 '13 at 9:49
Great, It is the single biggest mistake made by all non-native speakers I have heard. – mplungjan Feb 13 '13 at 9:51

'I didn't think...' is right, for present tense, and past tense is "I had not thought...." This is probably better on English language users:

didn't think is past tense. don't think or am not thinking is present and present continuous. had not thought is past perfect. – Jim Feb 13 '13 at 7:17
So you also have I wasn't thinking as a correct answer. As usual, the question which is correct depends on the context. And how about I thought not? – Mr Lister Feb 13 '13 at 7:33
