Can't save pages anymore.

I want to thank everyone for their replies. I'm truly greatful. Unfortunately, I can't really make anything from the advice. As I said I'm not very tech savvy, meaning if I'm to try something I need explicit instructions as in "Open X. Click tab Y. Type in Z" etc. 

I've also tried using a new software site akin to GIMP (not sure I'm allowed to say which one) but I can't open the files there either because they don't support XCF files. So basically I'm still on square one.

Thanks again, 
JT
