I installed the latest update which I believe was released yesterday, and I go to open PDN, and it says it cant open, So I go to reinstall it, and it says it can't download paintdotnet_x64.msi. which I find odd, so then I thought to look for help, it tells me to go to microsoft installation troubleshooter, and THAT says 404 not found. what can I do? I've used PDN for about 4 years now, and I've had no problems with it until now.
