Hi Amirah,
Regarding the paging file error were you also using Gen Studio on the model?
I am also thinking the update.trn symptom is similar to your other "random file access problem" thread: Find Missing File
Could these problems be due to anti-virus software as I suggested in that thread?
Is it possible to temporarily disable any anti-virus software you have running to test if the problems are resolved?
Regards,
Lynn
