These are two separate issues:
If there was a forced restart while VENUS was actively running (or a power interruption to the PC) then required files used at either edit time or run time can be corrupted when improperly closed. If you can post your VStar.cfg I can take a look to see if the issue is recoverable, otherwise the software may require a repair. To provide instruction I would need to know what version of software you are running.
The second issue is an inability for run control to connect to the VENUS SQL server and establish a run database. For further instruction and insight, I would check out the following posts:
