Hey guys! So my nspire CX CAS was working great before. I was using nLaunch to dual boot it with 3.1 as well as 3.2.3. However, my 3.1 OS got messed up somehow, and I had to reinstall it as well as run a NAND check to get it to work. This made my nLaunch not work (when I pressed the reset button after changing phoenix.old to phoenix nothing happened this time). So then I deleted it and installed nLaunch again, and that works fine, then I upgraded my ndless to the latest version by replacing the ndless resources file. That seems to work as now Nover 3 works, where it gave an error before about the wrong ndless version. However, now I cannot transfer any .tns file to my calc  . Every time I do it says "the transfer can not be completed because the handheld file or folder could not be accessed". I just know that with all my OS/nLaunch reinstalls I messed it up somewhere, so any help to get my calc working would be appreciated. Oh and btw, everything else works on the calc that's already there, and I've tried the student software and the computer link! xD thanks!

Indeed that sounds like a FS corruption, which may have been induced by going too much into the danger zone in Nover.
If not that.... I'm not sure.
I'd recommend saving everything if you can, then completely reformat the calc (in the maintenance menu), and try from scratch at a "clean" state

Well, actually nope. Everything worked fine for a day, I was able to get all my files back on the calc. Also nover is set to a much safer 234 Mhz. But it's now giving me the same error.
