Running out of tasks

Hallo!

Within about 30 min my PC will run out of tasks from application O2AS20-500.

Since Sept. 5. I don´t get anny new tasks. May be longer, because at this date the PC became restartet. But at the end of BOINC starting procedure I found 

05.09.2019 19:29:02 |  | Checking presence of 140 project files

but never I had 140 tasks in forehand. The preferences are set for 2 days, which means max 10 tasks in forehand.

The program is asking repetedly for new tasks, but don´t get them. The work generator is diabled, but there are about 5000 in stock. Why I don´t get some of them????

Kind regads and happy crunching
