I recently upgraded Mandriva 2009 to Mandriva 2009.1 on my netbook and previously was using KDE 3.5 but switched to KDE 4.2.
I went into the Add/Remove programs and went to mandriva-theme to try to install additional themes. I'm not sure what I did wrong but now I'm unable to boot.

When I turn on my netbook it goes to the screen where it lists all kernels and then it goes to a black screen shortly after with text.
It has a lot of lines saying achi: Unknown symbol
Below that it says:
FATAL: Error inserting ACHI (/lib/modules/2.6.29.1-desktop-4mnb/ahci.ko.gz): Unknown symbol in module, or unknown parameter (see dmesg)

That is the last that it says. I tried to reinstall Mandriva and select the upgrade option but then it just ends thinking it's installed. If necessary I will completely reinstall Mandriva but was wondering if there is something simple I can do to get it working again. Thank you.
