Crash after failed rule applied

Hi
I found a systematic bug that happens every time I try to apply a "wrong" renaming rule.
Steps to reproduce:
1) Define a TimeStamp rule like File Pattern, <Year>-<Month>-<Day>
2) Add a file that does not match: "testfile.txt"
3) Run batch
4) "Pattern not found" Error appears (OK)
5) Deselect TimeStamp rule and add a replace rule (whatever rule you like)
6) Start batch to execute the replace rule
7) Error 1: Access violation at address 00000000 in module 'ARen.exe'. Read of address 00000000.
8) Error 2: Invalid pointer operation.
9) Crash

Also note that it looks like Aren.exe process stays open in the task manager and it keeps using a lot of CPU

Finally got around to fix this one. This error should be gone in version 3.85.
