I assume you mean TMX and not TTX?  It might be helpful to see the TMX if that's possible?

Also what version of Studio are you using?

Also you have not provided all the error report.  A screenshot like this is interesting but not as helpful as the full error stack:

If you just want the TM reversed because you work with it yourself in both directions then you might find using AnyTM is easier.

Thank you for this. 

I am having difficulty undertandig how to use the AnyTM.

Can I use one AnyTM for all four TMs, UK English to Icelandic, Icelandic to UK English, US English to Icelandic and Icelandic to US English?

Thank you for this.

No, not one TM for all four.  Just add AnyTM for each TM you want in your project..  It basically lets you add any translation memory you like and will return results if it finds any.
