When loading up Abot's water life i get this Error message, can anyone give me a step by step on a quick way to fix it, i assume it is harmless.

One or more
plug-ins could not find the correct versions of the master files they
depend on. Errors may occur during load or gameplay

That error isn't a major problem, but if you want to get rid of it, it's very simple.

Load up the CS with Abot's water life. It'll load the esms that are required. I can't remember, but the CS might report the same error.
Once it's load up, resave Abots mod.

That error should then vanish in game.


Disclaimer - if your PC blows up, don't blame me

Ok so it is the water life Tamriel rebuilt addon esp that is giving me the error, and i cant seem to be able to resave it, do i need to change the name of the esp to resave? Or can i just resave over the original esp?

You just have to launch Wrye Mash, and click on the master tab of the plugin .esm to change his date.

If it's not clear, just download Wrye Mash ^^

That message just means a mod have been saved with masters dated differently from yours. As long as relative date of masters (= loading order of masters) is the same, this is harmless.
Anyway, to get rid of the warning, best procedure is:
Mash, select mod, click somewhere in right column white space, click save button below. This will update the mod with the date of your masters, and nothing else.
This way
1) you avoid the need to convert .esm to .esp to be able to edit from CS, and back
2) mod date remains the same even if you forgot to have Mash Lock Times ON
3) you don't risk generating unneeded cells/GMSTs when resaving from the CS.
[EDIT]typos... and connection hiccup

Fixed, thanks much!
