Like I said in my previous journal, I have tried virtually everything and nothing works. Does anyone know if maybe a file or program needs to be removed?? To make it work? I am literally stumped, I can't figure this out at all..

I need some serious help.
Ever since my computer forced me to update to windows 8.1, Paint Tool SAI has been giving me major problems with my tablet. My old tablet (monoprice) worked but didn't have any pen pressure what-so-ever and then my tablet stopped working all together. So I order a new tablet (Bamboo Capture Pen & Touch) and the pen pressure still doesn't work in SAI. I've tried every solution/fix I could find. I've uninstalled, reinstalled both SAI and my tablet multiple times to no avail. I tried going into the misc. file and changing the TabletMouseSimulation from 0 to 1. Note: with my first tablet it was necessary to do this in order for it to work with SAI but with my new tablet it doesn't need it. I tried updating my tablet to the newest driver yet nothing. I feel like I have tried every option but nothing works for me. I'm pulling my hair out trying to think of solutions. I was thinking of trying to downgrade my Windows but it was going to remove so much stuff on my computer. I am trying to work with Krita but it's hard to get use to. SAI was just the program I was comfortable with and could use without difficulty.
If anyone could help me out I would be so grateful! I feel like it's going to be a lost cause, that it just isn't going to work for me anymore but I'm holding onto what little hope I have.
Thank you.

I have a slight problem I guess?
I just finished this drawing for a story I'm working on and I want to post it but I'm not sure if I should post it before the story is done or after.
