I just updated to 1.5 but whenever I try to run Paintstorm it just pulls up the "loading" wheel and never opens.

My specs.
Windows 10
Intel I7
16 gigs of RAM
GTX960m

Is there any way to fix this?

Some of our customers advise to add paintstorm to ignore list of antivirus. Paintstorm try get internet connection and can be blocked by antivirus. Also you can try to delete paintstorm Documents folder and install a clean version
