Question:Error in solve, Maple 18

Hi,

I recently reinstalled OSX (from Mavericks to Yosemite), and since then, Maple wont solve. Neither in document or worksheet mode. I have never seen the error before, and cannot find any help online.

 

"

solve(x-8*(1/12) = 0, x)
Error, (in solve) invalid input: hastype expects 2 arguments, but received 1


> solve(x-8*1/12=0,x);
Error, (in solve) invalid input: hastype expects 2 arguments, but received 1


solve({x-8*y = 0, 2*x-4*y = 1}, [x, y])
Error, (in solve) invalid input: hastype expects 2 arguments, but received 1

 "

Restarting maple does nothing.

Anyone know what's wrong? My schools license for older versions of Maple are expired, so haven't tried that.

Thanks a lot.
