@hiranyakasipu Good to hear!
As for your other questions there were also price estimation issues with the old version. Those should be mostly fixed with the latest release. The main issue is that when you "buy" storage you are really just setting aside that money to use for future file contracts. Until you actually use that money, the price of storage will fluctuate with the market. That means the 10GB worth of storage the UI showed you a month ago is let's say 8-12GB worth when you go to use it.
As the market matures and price stabilizes this should be much less of an issue, and the old version of the UI greatly overestimated the cost of storage which is why it locked up so much. The bright side is that any SC you don't use at the end of the contract time will return to your wallet. I believe this is 3 months by default. In the mean time you can use the money you set aside to upload files as you normally would and be charged the going market price.
