You *can* continue your campaign, but it is likely screwed. At least your savegame is "tainted", so you should not report any more CTD bugs before you start a new campaign with the up-to-date map.rwm.

I've started a new campaign and cheated to get the Gordu settlement at the first turn, added population and proceeded to wait for rebellion. It rebelled nicely three times in a row (I retook the settlement in between of course), then I made a small change to the EDB file to experiment and CTD hell broke loose the next time it rebelled. When I reloaded the savegame after the first of the rebellions, the next one CTD'd. Even when I had changed EDB back to what it was originally! So it's pretty fickle...
