QuartusII 9.1 , Error: Can't read database file C:/.../.../db/MyProject.sta.rdb

Hello ,

I use QuartusII 9.1 (build 222 10/21/2009 SJ web edition)

I get the following error when I start to program the EPCS16 (for EP3C25) flash memory I have the following error message:

Error: Can't read database file C:/.../.../db/MyProject.sta.rdb

But the memory is still programed, and the FPGA runs properly.

??? Is it a problem in my project settings or others .... ???

Thanks in advance for your help
