Dear helper, After some cleaning, I found out that I cannot open my R2.6.0 console with message: "Fatal error: uanble to retore saved data in .Rdata", and every time I retry it just kick me off. I am wondering if I still be able to retrieve the data that I've been working for a month. I have installed the new R2.6.1 and it has no problem to open, only there is nothing in it I also wonder if I will be able to transfer all the files in 2.6.0 to 2.6.1. I appreciate anyone who can help. Thank you, Ilham
