problem with converting chemkin file into OpenFoam format

hi guys, I hope that you are doing well I stuck in converting my mechanisms from Chemkin format into OpenFoam format. You can find my 3 chemkin files in attachment. When I use chemkintofoam comand to convert the files to openFOAM format, I get the error: --> FOAM FATAL IO ERROR: "ill defined primitiveEntry starting at keyword 'N2' on line 1 and ending at line 50"

file: trans_chemkin.dat at line 50.

From function void Foam:rimitiveEntry::readEntry(const Foam::dictionary&, Foam::Istream&) in file db/dictionary/primitiveEntry/primitiveEntryIO.C at line 168.

I tried different tricks but no one works till now Does any body any solution for that? Thanks in advance guys C2H4_DNS_41Spec_.zip
