I have been having issues trying to purchase games off of PSN. I was able to buy 2 games but every time I try to buy Super Stardust I receive a message telling me the server connection was lost. Is anyone else having the same issue or know how it fix it (the system tells me to go online and see if the network is up in my region, I'm in the US so it always is).

I haven't heard about any downtime  and I just tested a download from PSN that seemed to work fine. 
 
- Make sure you've updated to the latest firmware since your previous two downloads. 
 
- This may be a problem with Super Stardust itself, so try to download a demo or something else to make sure it's not your system. 
 
- Check to make sure you have enough memory on the Vita.   
 
- Hard restart the system. 
 
That's all I can think of.  I seem to remember reading somewhere that PSN will be down for maintenance this evening for a few hours.  This may have something to do with it. 
 
Good luck.

I would try buying it from your PS3 or your PC and downloading it to your Vita, see if that works? I haven't had any problems buying and downloading right from the Vita.

Having the same problem myself. After purchasing 2 things in relative quick succession, now whenever I try to buy anything I get the connection lost error. All other web-based functions work fine and hard resetting did not fix it.
