The change in kernel version and therefore modules is the cause of this issue.
A new CorePlus cannot be made until such time as all included extensions are also updated to reflect the new kernel/modules. At present time ndiswrapper-modules-3.8.13-tinycore.tcz is missing.
Once ndiswrapper-modules-3.8.13-tinycore.tcz is available then an updated/corrected CorePlus will be made available.
