Feb 3 and Feb 4 crashing

Same here. Windows 8.1 Lenovo N585. Feb. 1 & 2 daily challenges worked great. All of Feb 3 is crashing and I was able to do the Expert Level on Feb. 4 daily challenges.

Good news: today (Feb 5) all 3 challenges are working.

Bad news: the corrupted challenges from Feb 3 & 4 are still crashing the app. :-(

Hope they'll fix them soon, as I believe many players worldwide are keen to maintain their 100% records.

I had the same problem with this challenge, and today (4 Feb) the medium challenge crashes.

Before applying the update: one more corrupted challenge - the Feb 7 3-star Classic, so in total 4 crashing challenges now.

Will see if the update fix them.

1. The following daily challenges are not loading:

a. 3 Feb – Tile 1 – Easy – Classic

c. 6 Feb – Tile 1 – Easy – Golden Tiles
