Hi
First please tell if you are using all Api, i.e. if you reach your limits in all translation providers, the data will stay untranslated until translation will be available again.
Please also check your ttl for cache, if you are not using Google API v1 you can even turn it off(0 = disable)! So cache won't be deleted
admincp -> vBET Cache -> Database Cache -> Cache Time To Live (TTL)
Moreover I can see that your translation didn't work at all, please check if you reach your limits by using those tests http://www.vbenterprisetranslator.co....html#post1728
Also make sure if you have upload all needed files (also this from upload once folder)
Meanwhile i will try to reproduce with "dissaperaing" translations
