A fatal exception occurred.

Greetings!

I attempted to use the OPUS-CAT Tool but it seems that something is wrong with the file I have downloaded. Or then again I might be doing something wrong. Do you have any ideas on countering this issue?

Hi,

This is related to the file database that OPUS-CAT uses to cache translated sentences (so that they can be generated in advance). For some reason, the database is in readonly state when OPUS-CAT is trying to edit it. This should normally be resolved by restarting the system, but if it reoccurs, something else is going on. It might be that the user permission setup on your system is somehow strange (the database is stored in your %localappdata% folder, and you should always have permissions for that).

You should be able to bypass the problem by disabling the database caching by editing the config file OpusCatMTEngine.exe.config (in the MT engine folder that you have unzipped). Search for this bit of code:

<setting name="CacheMtInDatabase" serializeAs="String">
               <value>True</value>

and change True to False:

<setting name="CacheMtInDatabase" serializeAs="String">
               <value>False</value>

I'll log this a bug, the caching should probably be disabled automatically in these cases.
