NWDSI 7.0 Not responding

Hi Experts,

I am using NWDS 7.0.

Here I imported an WDJ DC from NWDS, after  that re-imported the model of the particular DC. Then I tried to build the DC. It was taking too much of time. so I closed the NWDS from task manger , I am having an open activity for the same( for model re-import).

But here come the tragedy, after that when I open the NWDS, its not responding even for hours.

How to resolve this problem.

If I delete the .metedata or .dtr or .dtc, this will affect my open activity. also make in-consistency for the open activity.  Help me on this inconsistency.
