Dsp builder error in matlab R2014a

[Altera_Forum]

I try to add dsp standard block from simulink library broser to simulink model file and I have an error in matlab command window: 

Problem occured with mask object. DSP Builder cannot find the Java classes it needs to work. I can not save my simulink model file because i have an error.  And i have no error when i add an advanced dsp block to simulink model file. )) What need to do to fix that?
