FRM1001 The input line type is invalid.
Explanation
Corrupted form. The form loader is hanging on a line
with a certain first character, because every line in a form file,
according to the form file format, starts with certain character (T,
V, R, H, E, *) that define the line type. The current line's first
character has an unknown type.
User response
Try to open and save again with exact same version
of QMF that
was used to create the form.
