Mod in stall with latest version

[ctekk2005]

Been trying to install mods with the latest version..

Keep getting this error message

The package you are trying to download or install is either corrupt or not compatible with this version of SMF.

Anyone got any words of wisdom.

there are many reasons why that happens. here are a few examples.

what is the version of smf you have to make sure that the mods that you are downloading are compatible with the version of smf  

and if you are using a third party mod site then

Delete the "Simple Machines Third-party Mod Site"

Add a new one with this address: http://custom.simplemachines.org/mods
