I came across a similiar problem recently. We were using Quartus II v4.2 and the project compiled and worked no problem on an Altera EP1K50QC208-3 device. If we compile exactly the same source code using Quartus II v.9.0, the project will compile ok. Download to the same device and the device won't startup and running until few mins later.
