activemq-data corruption

Our server that hosts Mingle had an abrupt power failure that pulled the plug - no clean shutdown.  After rebooting, Mingle refuses to start.  The error log contians errors about active-mq (at end of post).

To "fix" this, we installed a new mingle installation, and copied its activemq-data folder over the one containing our "real" mingle installation.  Mingle now starts, and everything appears to be working ok, but I'm a little nervous about our "solution". 

What are the implications of what we have done, and is there a better way to fix this problem?

We are using mingle version 2.3.1
