NFS Unbound - error code "FTCL50001"

I won't be editing the previous one cus thats too big to read.

I tried changing the save file, but sadly I can't help you with that now. If you've read the previous msgs here, you'd see one of mine where I said that I wasnt able to play the game or it wasn't just launching for me. That's what happened when I replaced my save file and the game didn't launch. Tho I'll still try out and see if I get any results from it.

It just occurred to me after your mention on progress. I had kept everything I had, the levels, progress, cars, as I mentioned before, but, I didn't seem to have my bank. Back to the start of it with 200k. And also, had to select a starter car again, but, my other cars were still there. As for the cars part, idk what to say, since the cars that I owned, were a few, Audi S5 (idk where or when I had got it), R8 from the pass, and F1 from dlc. As for the starter car, I choose the gtr V-spec. That's all I've.

I won't be able to clarify more on this part sadly since I didnt had enough progress in online as I wasn't able to play it. The only thing I can say now is that I'm able to play online back.
Ima just recommend to keep the save file with you properly. Or if there's someone who could try this and share their results.

!!! [EDIT]
I was able to start the game with my save file which had my progress. Apparently, wasn't able to play online. I tried my recent different saves where online worked, of which, the new parts or upgrades that I had done to my starter vehicle were only with the save file with which I was playing, but not with the one from yesterday. So, whether it's just this, or it affects everything, I can't be sure of it now, unless someone else actually tries and tells us about it. KEEP YOUR SAVE FILE PROPERLY.
