Problems adding EPS file to PostScript::Simple
%%[ Error: undefined; OffendingCommand: ÅÐÓÆ ]%%
The "offending command" ÅÐÓÆ (C5 D0 D3 C6 in hex) is the typical identifying characteristic of an EPS file containing a TIFF/WMF preview thumbnail (see Identifying EPS files).
Not all tools can handle such extended EPS files correctly, so the above ID may end up being mistakenly interpreted as a Postscript command. You could try either creating the EPS file(s) anew without a preview image, or use something like epstool to extract the pure-EPS content from your existing EPS files.
