Grading conditions missing

[Stephen J. Weihman]

Not sure how or why, but most of my grading setup conditions for grading companies are gone.  I don't have CGC, CBCS or PGX standard grades.  Is there any way to add the grades and % of NM values easily?  If not, is there a chart showing what the standard %'s for each one are?

Okay, found the way to add the grading companies.  Took a bit of cajoling, but got it to add them.
