There seems to be another problem with the wallet:

My actual balance is
7.999 MSC
10 TMSC
0.10268 BTC, see
https://masterchest.info/lookupadd.aspx?address=1CHoqNqBmYgxFX3wuoJYfGw4rVAbeRWPcU

Furthermore, I should have received a few thousand maidsafecoins, see
https://blockchain.info/address/1CHoqNqBmYgxFX3wuoJYfGw4rVAbeRWPcU

Instead, the masterchest wallet (version Alpha 0.3C Build 0025) shows:
9.37205714 MSC
11.37305714 TMSC
0.10238 BTC

So, 1.37305714 MSC / TMSC more than I actually own.
What could be the reason for this error? And why are no maidsafecoins displayed?

Thanks!
