Thank you very much, but this file current_oplc.udb does not exist in the Unitronics folder of my computer,
however, there are files called New_OPLN_BW.ubf, New_OPLN_V130.ubf, New_OPLN_CLR.ubf, perhaps they be deleted?
- I have tried reinstalling according to your instructions but I get the same error.
Another idea for this trouble?
Thanks again..
