Welcome Helopilot59!
You should be able to get get the 1.5 upgrade from UBI's site. It's rather inexpensive now. I got it 4 years ago for around $10.00 US.
TMO 1.9 wasn't made for SH4 1.4. If memory serves, version 1.6.2 was the last version that was made for 1.4.
I think I was able to get it to work with 1.4, but I had to make some modifications to it, or SH4 itself to get it to work, but that was long ago. I have had the different versions of it since 2.0 it first came out, and I cleaned all my old versions out some time ago, as I was running ot of space on the old hard drive.
I wish I wouldn't have though, as i added a 1TB drive back in December, and could have just moved everything over to it then.
You can try a google search to see it is still available somewhere.
