BackWPUP 1.7.3 just stopped working all of a sudden

This started yesterday and trying to do a backup manually results in the same error.

6.12.11 – OK – Database only
6.13.11 – OK – Database only
6.14.11 – OK – Database only
6.15.11 – Not OK – 2011-06-16 03:01.09: [ERROR] Backup Aborted working to long!!!

6.16.11 – Not OK – 2011-06-16 03:01.09: [WARNING] Working Job will closed!!! And a new started!!!
2011-06-16 11:50.13: [ERROR] Backup Cleand by User!!!

6.16.11 – Manual – Not OK

2011-06-16 11:50.35: Add Database Dump to Backup: *.sql 88.67 MB
2011-06-16 11:50.35: Create Backup Archive file…

and that’s it.

Now it vacillates between create backup archive and backup cleand by user. Whatever that means.

Any ideas?

thanks in advance,
