Ok, I have no idea what I'm doing wrong so maybe SOMEONE can help me. When this update first came out in January, I downloaded it, had no problem and worked perfectly. A couple weeks ago, my n800 crashed and resulted in my having to reflash it. Unfortunately I can no longer get this working I can download the installer fine, but whenever I run it, it says "Unable to install.
Software contains updates to packages installed from a different source and is likely to harm the system.
Contact software author.
Continue installing?"

When I click ok it loads for a second and then says "unable to install rtcom-beta-os2008"

Any advice?

UPDATE: Now it seems that I can't install ANYTHING not even first party nokia apps...
