PolloLoco: I had heard that there was an issue for a couple people with bubble breaker in PR6, but for most it worked. Since its the same Rom, it had to be a 3rd party app or something on the phone itself (extended_rom?) Never was able to get it to reproduce for me me so could never look at it.
As to PIE+, the only way to make it work since you did not update your clock prior (I warned about that) is to register the app (or hard reset and start over). IE should work fine, you just won't se the PUE+ features. I use IE alot and would recomend purchasing PIE+ as it really is nice, more so having tabs in the browser and to be able to load pages in the background (Links from google searched for example).
