Quartus II Internal Error -- Please Help!

I am using Quartus II 64 Bit Version 13.0 for my project on the Arria V GX Starter Board. I am designing a transceiver which would accept 1.25gbps stream of data and see if the data violates the 8b/10b encoding scheme. I have created "Arria V Transceiver Native PHY", "Transceiver PHY Reset Controller" and "Transceiver Reconfiguration Controller" modules and am trying to instantiate them all in the top level entity file called "top". However, during simulation I am running into the error given below. I would really appreciate it if someone could help me out with the problem. I can provide more info as necessary.

Re: Quartus II Internal Error -- Please Help!

One of the possible root causes of this IE is that your design contains Receiver Only channel with Rate Match being turned on. Rate Match FIFO is clocked by the clock from the transmitter channel of the same physical location, therefore, if the use of Rate Match FIFO is intended, you will need to create a duplex channel. Otherwise, just disable the Rate Match FIFO. 

Let me know if this works.
