Ida Pro Problem

I hava big problem, when i put the exe "RobloxPlayerBeta" on IDA PRO, give me a warning like "The import segment seems to be destroyed.. etc..".
I go on View < Open subviews < Strings let IDA load the strings and when i search like "WalkSpeed" the result show nothing. 
I did this a long time ago and worked, and now it doesn't why?

Thanks.
