Memory error

Hello,

I try to recover files from a deleted partition of my USB HDD.

When i start the program it showing the normal things.

When i select the option to search all, after a while i get the announcement, that it has not enough memory.

When i select the option documents only same error appears.

What i did was installing the program on my C drive. After that i installed the program on a spare drive with 1 TB space.

The HDD i want to recover is 500 GB so in my believe i must have space enough on my new drive.

Anyone have a clue whats causing this problem???

Thx in advance
