Error 602 "Error opening project" MultiTerm Extract 2014 SP2

Hi,

When I close a project in MultiTerm Extract and then I try to re-open it, I get the message Error 602 "Error opening project". What is the issue here? How do I solve it?

MTE is a very useful tool, it is a pity that it is not maintained and boosted.

Thank you and regards.
