I'm in a jam...

[Pat D. Stephens]

Can anyone help me?  I'm trying to backup files from my book that needs 
to go into the shop and ordered and am trying to install Retrospect 5.0 
to do a complete backup on CD.  After installation, I get a system bomb 
and it tells me to start without extensions, but when I do, I get a 
message telling me to that it needs InterfaceLib and to get an updated 
version.  So, I can't get it to work.  I called their Tech Support and 
she tells me to call Apple and I can't...the care plan is from another 
company.  Can anyone give me any hints?  I'm running 9.1 on this 
machine.
