Item #24 - Can't restart a backup due to java.lang.ClassNotFoundException: com.arecavss.plugin.ArecaVSSFileSystemIterator [Closed - Resolved]

When I want to restart my backup after a network failure I receive the following message:
---------------------------
Pending archive detected
---------------------------
A pending archive has been detected by Areca
(Transaction point : //BackupServer/BackupShare/areca1/555555555/dddddddddddd/222222222222/ffffffffffff (//BackupServer/BackupShare/areca1/555555555/130509_data/transaction/00000001129))

Do you want Areca to resume this archive instead of starting a new one ?
---------------------------
Yes No
---------------------------

When I click "Yes" I receive the following error message:
---------------------------
Error
---------------------------
The following error occured during the process :
java.io.IOException: java.lang.ClassNotFoundException: com.arecavss.plugin.ArecaVSSFileSystemIterator

Please check the log file (C:/Users/UserName/.areca/workspace/.log/areca.13-05-10.log) for further informations.
---------------------------
OK
---------------------------

Due to this error with ArecaVSS I can't reuse already backuped files and I need to start more-than-10-hour-long backup process over. It's very disappointing.

My OS version is Windows 7x64 SP1.
The rest of the information can be found from the logs below.

Hello

This is not a bug in ArecaVSS, but in Areca-Backup itself.
The dev team has just submitted a new version that should fix the problem - please try with this new version of Areca.

Best regards
ArecaVSS staff - 2013-05-11 11:09
