i need help with presets

The thing I see all the time with this is that the presets include third-party plugins that you (OP, etc.) do not have installed. 

Even if you do have the third-party plugins installed there are still other variables it can be. You simply don't know what you're getting when you download presets from the internet unless they are coming from a reliable source. There are so many combinations of what they could be, versions they were created in, Mac or PC, what versions the third-party plugins are, etc. It makes this issue rather difficult to troubleshoot. Piracy and cracked software are also a rampant issue surrounding this (Sapphire is a popular plugin, for example, and comes with an incredibly high price tag for a hobbyist, so lots of people using Sapphire effects are using cracked software, which is not something we're going to be helping to get working here - or at least I'll speak for myself there.)

The fact that you can import some presets - presumably without third-party plugins - means the import function is working and it's most likely the plugin-related reason.

Where did you get the presets? How are you importing them?
