There will be a pledge management site set up in the next couple weeks, as well as a mailing list for Paypal backers, and a Kickstarter update sent out with details on that.
How did you try contacting Larian? There is nothing from you to any of the game specific email addresses, and I've had one email to the general support forwarded to me this morning, so that is probably everything to the support/info email addresses from over the weekend... the kickstarter email address may not be checked frequently any more.
