Ok, sounds good.

As you mentioned Hung, that's the one part of the issue that I have yet to figure out because JLink v5.00 should work as well. I'm guessing it had to do with v5.00 being installed during another program's installation.

Good to know, Michael. I am using Segger Jlink v5.00 but didn't have the issue.

Regarding nrfjprog, I don't think we have any further documentation that what we have in the --help screen. You can post a question if you stuck at something.

The nrfjprog.exe tool looked interesting in the short time that I looked into it. Is there any literature for the tool other than the -help (I think) drop down descriptions?

I finally figured out my issue after I stopped looking into it for awhile. After I had installed Nordic software I installed software that called for Segger v5.00. At the time of writing this nRFGo Studio is using Segger v4.98c. Windows registry for Segger was changed to v5.00 and I'm guessing nRFGo Studio kept looking at v4.98c (This is a paraphrase, I'm not an expert on the registry). Even after uninstalling all of the software that I had installed, the registry for JLink was kept at v5.00. After I went into the registry and changed Segger/JLink/InstallPath back to v4.98c my problem was solved.

I hope this helps someone who has the same problem as me. I found out about this registry problem by reading someone else's self fixed problem. I have an inquiry for more information, so if a Nordic employee sees this I'll post that inquiry as a comment.

A tablet could be an issue. We haven't got much test with using nRFGo Studio with tablet.

You can use nrfjprog to program, verify , erase, pretty much anything that nRFGo Studio can do.

I don't have another computer that would work right now, I just have this computer, my work computer, and an asus tablet that doesn't have the best performance/capability; but that's a good idea. I tried installing an older version, it errored, that might have been because I had a newer version of some other software or a newer driver.

I uninstalled all of the programs and drivers I've installed recently since this issue began, because something I installed messed the nRFgo studio up, re-downloaded all of the Nordic software and installed from scratch. I still have the same issue.

I don't want to erase the chip because I have S110 on currently, which I think is the Softdevice I wanted to use, still this problem is upsetting. Do you think I can use the cmd tool to figure out my issue? I just opened it up and am reading it now.

@Michael: It's pretty strange the issue you are having. Have you tried to connect it to another PC ? You may also want to try instal nRFGo Studio v1.19 for testing. To downdload different version of same program you can click on the version number.

If you couldn't make it to work with nRFGo Studio, the temporary solution is to use nrfjprog.exe tool. It's a command line tool and nRFGo Studio uses this tool to program, erase the chip.
