Yea probably, theres nothing really worse about 3.1 as far as I know. It doesnt block ndless or give inability to downgrade, so you might as well.

I've received your PM but I still can't reply it there so I will reply it here. Yes I'm interested on programming in my CAS but actually I'm more interested on upgrading it to run some new scripts there.

Shoud I need to install before the downgrade fix? http://www.ticalc.org/archives/news/articles/14/147/147473.html
