Maple messed up my MuPAD Matlab integration

Question

I have installed a trial version of Maple recently, it has expired and I've already uninstalled it. But today, for my surprise, Matlab symbolic tool is not working properly anymore, I was able to find using google that Maple changes the symbolic tools for its own (without warning or so). But it is not undone after uninstall.

The question is, how can I make Matlab "find" MuPAD again?

error e.g.:

symengine
//Undefined function or variable 'symengine'.
