Help with 1.5.2

[SXScarecrow]

Hey guys,

I'm in the process of updating my modpack to 1.5.2, and I have come across this error. It won't tell me which mod is crashing, or why, and I can't make sense of it:

Please can someone explain this to me?

That's not a full crash report, copy the WHOLE thing and put it on pastebin.com then send me the link.

[SXScarecrow]

Whoops, my bad. Here you go.

Crash Report

[Amaxter]

Looks like you forgot to copy the last part of the crash report . Pastebin again.

[Amaxter]

Wait, I see the problem. Looks like your one of your mods is not compatible with your version of MineCraft.

[SXScarecrow]

It would be helpful if you could tell me which mod it was, and how to spot the error if it comes up again. I don't particularly want to take it all apart and put it back together again. Also, quick tip, the moderators and admins do no appreciate double-posting.

[Amaxter]

Sorry for the double posting, yeah I'm really tired! As for the mod I can't tell because I don't have a full crash report. You didn't Pastebin it all. Try again and make sure you include the bottom bit.

[SXScarecrow]

This is the full ForgeModLoader log, there isn't anything else I can give you.

Log

EDIT: Reading my log I realise that it crashes at the Fluid Mechanics stage, but it cites that Basic Components is the reason (BC is not in this modpack). I will investigate this further myself, if you got any tips, I would be happy to hear to them.

[Amaxter]

Try removing Basic Components, it's not needed in 1.5.2 anymore, now it's just an API for mod developers.

[SXScarecrow]

Oops, you posted before my edit. Basic Components isn't in this modpack, which perplexes me.

[Amaxter]

Tinker around and try using different versions of Fluid Mechanics, also Fluid Mechanics is incompatible with a lot of mods that modify liquids like the Weather mod. Give me your pack URL and I can help you a bit more. As for Basic Components it IS in the modpack, it's just packaged in with the Universal Electricity mods now.
