Hi
I have been having issues with Crystal Reports (XI)
1 I am using a jdbc connection and Connector/J 5.1.33 (java).
This worked for a couple of days then failed to retrieve data from the database then to missing driver so fixed that by using an earlier version of jar file 5.1.15
2.Now database I am using is showing up but sometimes i can pull one table with no issues or I cant pull any tables and errors in the attachment below
How do I fix this once and for all
(other info only one of the computers is having this issue
