Hi, FICO. We recently upgraded to Blaze 7.5 and now we are unable to view, change, export and import decision tables. We see the screen as in "attachment1" and when we open the table directly in Eclip

It looks like you have some issues about how your instances and templates are bound together, so there were some underlying issues before you upgraded to Blaze 7.5. You likely are going to need to find the source of these problems in the version of the repository before upgrading, correcting it and then trying to upgrade it again. I would recommend contacting support to see how they can help you in this process.
