Counter-Strike 1.6 HLTV Demo Fix

I have a corrupt HLTV demo that I need fixed for a movie. It works for the first 28 minutes then stops playing, right before the section that I need. This error then appears in the console: Last 32 messages parsed. 35776 0000 svc_time 35776 0005 svc_clientdata 35776 0006 svc_deltapacketentities 35780 0000 svc_time 35780 0005 svc_clientdata 35780 0006 svc_deltapacketentities 35784 0000 svc_time 35784 0005 svc_clientdata 35784 0006 svc_deltapacketentities 35786 0000 svc_time 35786 0005 svc_clientdata 35786 0006 svc_deltapacketentities 35786 0087 svc_pings 35786 0123 svc_sound 35786 0136 svc_sound 35786 0148 svc_sound 35786 0160 svc_sound 35790 0000 svc_time 35790 0005 svc_clientdata 35790 0006 svc_deltapacketentities 35793 0000 svc_time 35793 0005 svc_clientdata 35793 0006 svc_deltapacketentities 35796 0000 svc_time 35796 0005 svc_clientdata 35796 0006 svc_deltapacketentities 35797 0000 svc_director 35797 0013 svc_time 35797 0018 svc_clientdata 35797 0019 svc_deltapacketentities 35797 0153 svc_foundsecret BAD: 154:svc_bad Host_Error: CL_ParseServerMessage: Can anyone help me fix it thanks?
