error when adding a additional pattern Cuka

[AngelesGDelaTorre]

I am using data from a Bruker diffractometer with CuKa1.
When analysing a single pattern, everything goes fine.
When adding a second pattern to be analysed, when chosing *.instprm file this error appear.
Could you help me?

@AngelesGDelaTorre Could you make the .gpx file where this occurs available to me? It could be zipped and attached here or e-mailed directly to me.
