What is it that you are using the BizSpak program for?
Is it to build your product/solution?
If this is the case, then you are being too slow bringing your product to life... as Tim mentioned, this might indicate that this venture is already dead!
Can you explain a little more what is it that you're doing and what are the longer term plans?
You get to keep your Visual Studio licenses, and you must buy SPLA licenses (or the similar at that time) for your production servers. SPLA is not low cost, but then again, BizSpark is intended for startups wanting to become successful companies, not hobby projects.
