Ouch. In TLsuperposition.asc, there are three lines that define the
transmission lines:

SYMATTR Value Td=1.1e-6 Z0=50
SYMATTR Value Td=1.1e-6 Z0=50
SYMATTR Value Td=1.1e-6 Z0=50

Looks to me like whatever technique you used to save the file
substituted
'=3d' for '='. '3d' is the ascii encoding for '=' so maybe '=' is
treated specially.

Since these are the only '='s in the file, perhaps manually editting
the '3d's
out will fix the problem.

What tools did you use to recover and save the text?
