Tekkit will not start

[Lara Craft]

I just started having this problem yesterday, it was working fine until yesterday night. For some reason Tekkit will not start at all now. I go to the launcher, hit play and then nothing. It shows the progress bar next to the play button for about a half a second, but then it disappears and tekkit does not load.

Once and only once, it gave me an 'error read timed out' message, but this was a unique occurance and has not repeated itself, whatever the cause of that individual occurance is as good as random to me as I have been unable to duplicate it.

I have no idea how to troublshoot this or what the problem may be, or where to look to discover additional information. It's as random as all hell as far as I'm concerned.

Any help would be greatly appreciated, thanks muchly.

Okay so additional information.

I tried deleting and reinstalling the modpack, it won't let me reinstall it though now because it says it cannot delete frm the cache:

C:/users/Amy/AppData/Roamin/.technic/modpacks/tekkitmain/mods/1.6.4/CodeChickenLib-universal-1.6.4-1.0.0.61.jar

So if I'm reading this properly, the problem is something stuck in the RAM or soemthing ish???
