Good job !!!! So are you going to wait until prequalifier come back up ? Maybe in a few days it'll be back up. If your not too concerned about Apr, you can just cold app as you already know your good on approval. But as always, do what you feel is comfortable to to you. Nothing wrong with waiting for a week to go by. Your choice 
Strangely, I tried the pre qual at Cap One again and I got the fixed APR's. Apped for Venture first and got this:
Thank you for submitting an application for a Capital One credit card.
We attempt to provide an application decision in 60 seconds or less. On occasion, system availability affects our ability to make a credit decision or, in some cases, we need to collect additional information. Unfortunately, we need more time to look into this for you.
Keep an eye out for additional details regarding your application via email or mail within 7-10 business days.
Until we contact you, please do not submit another application.
Then hit app for QS and got this:
Thank you for your interest in becoming a Capital One customer.
Unfortunately, we weren't able to approve you for this card. Recognizing this isn't the answer you were hoping for, we want to help you understand why and have explained the reason for the decision in a secure letter. You will receive the secure letter via email within a few days. If we are not able to reach you by email, you will receive the letter in the mail within 7-10 business days.
Not sure what to do now??? Probably should not have hit second app.

Your first app could very well be a verification issue. I'm sorry to hear about your second app. Usually their prequals are pretty solid.
You had mentioned that your prequals had changed from one day to the next then back again. What's weird is I had app'd for the Freedom, CSP and Amex ED on the 15th. I only got hit for 1 HP for both Chase cards thankfully, and then another for the ED. So 2 Hps on EX. Anyway I'm rambling... that day I was pre-qualified for the Venture/QS on Cap1s site. I had waited to apply for those... The following day the 16th my prequals changed to the QS1/Platinum and have stayed the same since. Immediately I thought oh no they saw the 2 HP's. I just find it odd. Considering from what I've read they do have pretty solid prequals. From what another user told me it's from the CRA's and they don't SP when you actually use the tool. Either way unfortunately it's not an 100% approval.
Again sorry to hear the denial on your 2nd app.
Still waiting on my CSP app answer too btw.
