[Need help newbie]

I have had my license for 3 years but my friend programmed all my radios and passed away.  I cant seem to program the radios properly to work and need help.  I was approved to use numerous repeaters years ago but all that info is gone. 

 

I have 1 working radio that was programmed by my friend but I cant access the software to pull up the seetings.  Ive been working with mfg. Retevis but they cant seem to help.  I have 1 working retevis RT-9000D radio but I cant get software to read the radio.  If I can bring up the settings I can program the other radios I have.

 

I have 2 btech uv-2501 and uv-5001 radios that the software works but unable to understand the settings to program.

 

Any help out there for me?

 

Thanks
