Apple II

I was able to successfully bootstrap Speediboot, and made a ADTpro boot floppy for my Apple IIe. I used the disk image ADTPRO-2.0.3.DSK from the ADTpro/Disks folder for the boot floppy. I booted my Apple IIe ADTpro client, pressed R to receive a desired file, and it gives me a HOST TIMEOUT. I tried several times, and verified the the PC client shows a connection. It errors out each time.

I have my Apple IIe connected to my Windows 10 (64-bit) PC via a straight through cable , and a DB9 to USB converter cable so that it connects to my PC via USB (purchased both from Retrofloppy). When I start the ADTpro.bat file, I get the screen to select the configuration. I choose Serial, and it only shows COM3, and two possible baud rates. When I select COM3 with teh default baud rate, the screen closes and an error log is created in the ADT directory. The error message is as follows:

So I bought one of these about a month ago and put Total Replay on it and it works great... however, I cannot get any other files/games to work.  The instructions say "The BOOTI card is a block device emulator that allows you to mount up to 8 devices in any Apple II (II/II+/original IIe/enhanced IIe/IIgs). Disk images can be in .po/.dsk/.2mg/.iso/.hdv/.do, as long as the image is in ProDOS block order (not track/sector order)."

I am working on an AppleII + power Suply that is universal. And I don't have -12v. I replaced all the electrolytic Caps in the secondary section with no joy. Hs anybody worked on this problem in the past. I have a schematic, not sure if it is the right schematic butit is for  Aztec and it is euro. It says IIe so it is a more modern design than mine as I don't have Riffa caps in there.
