USB Blaster problem

Hello, I have a chip USB Blaster Rev C. When I program CPLD EPM7064SLC44-10 with Quartus II sp2 12.0 programmer, the process bar goes to 100% and then it shows "Failed". How can I fix this erro...

Finally, I fix my problem ! The solution was to connect USB-Blaster directly to CPLD (through 74HC244), connect VCCtarget and +5Vcpld together and add a pull-up resistor to TDI pin. The both programmers(my USB-Blaster and also Terasic USB-Blaster) are working now.

Thank you very much,

Yaroslav.
