A:(you,enjoy)--the concert last night?B:very much,I (go,not)

A:(you,enjoy)__the concert last night?B:very much,I (go,not)__to a concert for a long time.
我的填充是A:Did you enjoy B:have not gone
但是答案不对.我的想法：有last night应该表示过去式.后面for a long time应该表示现在完成时态.
但是答案却是A:Had you enjoyed B:hadn't went.这是为什么呢?求回答.TKS
