You could try this:

Windows key / Actian PSQL 12 / PSQL Monitor / Local Client / right click MicorKernal Router / properties / performance tuning / un-check use Cashe Engine

You might try this where you stop and then start the Actian service.  See:  https://support.na.sage.com/selfservice/viewdocument.do?noCount=true&externalId=25359&sliceId=1&docLink=true&languageId=&isDocLink=true&currentmsID=MS_Customer&cmd=&openedFromDocument=true&ViewedDocsListHelper=com.kanisa.apps.common.BaseViewedDocsListHelperImpl

We usually have to do this at the workstations after our server restarts. 

ok.. I did this and now the error I get is you can't open this application because the security files have not been upgraded. 

First use File Tools to Backup all files in your company folder.  Then, Common Tasks - Tools - Upgrade Files and be sure to click All files box.
