Yesterday I got a new computer with Windows 7 Professional, and my Intuos2 tablet seems to be having trouble with SAI. It's alright in Photoshop, but whenever I open a new file in SAI and start drawing, it'll come up with this error:

Sometimes it won't even create a new canvas before the error comes up. However, if I draw using the mouse, it works fine - it's only when I start to use my tablet that the error pops up. Is there any way I can resolve this? I've tried modifying misc.ini and that doesn't seem to fix it. Thanks!
