i cant restore my site with snapshot

I have followe diferent threads that i've seen in forums about this and i couldnt get it.
I use ftp in order to upload the snapshot created yesterday,...
I have created another wp instalation from scratch and also multisite, i have installed snapshot, i have uploaded locally the file, comes out a message of success in green , and then when i try to restore it doesnt work.
Could you help me with that. If you want i can grant you access , i think it could be easier to solve.
